I have two of these and I love it when the rifle goes into tune. It doesn't make a sound when firing. When it's out of tune it's like a tuning fork going off every shot. This brake basically takes out the need to move the bullet in and out to find the seating depth the rifle likes. You can make it even smaller a group by adding that in, but really 0.2 is fine for PRS. I have had no issues with repeatability. Erik stands by his product and at F-Class and PRS matches I see a ton of EC tuners, because he makes other styles and calibers.

I have it (in polished stainless and would rather have black) and I ran a very comprehensive test. There is no doubt that it works exactly as advertised and designed. My range was from around 3/4 moa to inside 1/4 going through the settings. My sweet spot is at "4" and it's good still at just past 3 and just short of 5.

Gavin i have the original Ec Tuner on my custom 6xc just like everybody i was a little skeptical to but had the gunsmith install it on a Bartlien heavy varmint on a Defiant action. All i can say is this gun is a tack drive went through some test and settled on number eight, shot a five shot group at 100 yards just under 1/4 inch group, did this test a couple more times same results, it’s made me a believer.
WORTH IT'S WEIGHT IN GOLD! I threw it on did some load work up found a good load 144 Berger and H4350 SD of 2.4 on my magneto speed. Loaded up 30 rounds took the magneto speed off and started fine tuning.3 shot groups starting at 1 to 8. Found it grouped well at 4 and 5. So I split the difference and wow! 5 shot group @.18 inches and .22 inches. Absolutely amazing product.
I bought a EC Tuner for my Remington 700-7mm REM Mag elk hunting rifle. My results were definitely similar to yours. My three shot groups went from .815 @ 100 yds to .279” @ 100 yds. I did have a setting where my groups opened up to over 1” (1.40”) then back to my best grouping. As a side note I was using IMR-4831 powder and Nosler 160 gr Accubond bullets.
I started reloading this year and I have an EC tuner break on my 300 wm. The best I could get my reloads was a half inch group but by using the EC tuner I’m now shooting 1/4 inch groups. With factory ammo my gun will shoot 1 inch groups but the EC tuner will help me get them under a 1/2 inch groups. My rifle is a Christensen arms ridgeline. I have also changed the stock. With the stock change and the tuner break it kicks less than my 7mm-08. I enjoy watching your videos because you are very informative. Please keep up the good work.
Bought an EC tunner for my 6.5 cm. My biggest surprise was reduction in recoil. I was surprised it has less recoil than my suppressor ( Gemtech 300 win mag). My last 3 shot group was .218
I have the 30cal brake i swap on 6cm 6.5cm and 6.5-300bee. Set to original settings and it stays true. Takes half of the work out of load development. Erik makes an amazing product.
I was wondering if the 30 cal brake would be effective on lower caliber rounds, that is how well it would work to reduce recoil and tune .280 and .270 cal rifles. Sounds like it works on your rifles.
Bought one of these for my .338LM. Worked amazing, love it. Loved it so much I just ordered another one for my 6.5CM. And I can't wait to see how much it changes things on an already great shooting rifle.
Another killer aspect of tuner is if you run data in temp changes and record it, you can tune load in colder/warmer weather. I run a 6.5 Lapua for PRS and it works. Without having 2 different loads.
For those weary of the tuner brake; buy one and install it as if it were a standard brake. Develop a load conventionally with a powder and seating depth node that shoots well. When you go to a match and your groups start opening up because of throat erosion or change in temperature/pressure, you can adjust your tuner on the fly as a backup. I think this thing can cut your load development time in half. It would be so nice to find a powder charge with low sd and then you could essentially finish your load development in 1 day at the range as opposed to making a bunch of trips back to your reloading bench
Easiest thing to do would be to have a tuner for each rifle. But, I like the repeatability idea for those on a budget and want, or are limited to, that capability. I'm a fan of Erik and have learned a lot from his channel.
I picked one up a while ago and it works wonders on my rifles! It saves me a lot of time and money so I don't have to play around with bullet seating depth especially when getting components are hit and miss.
My first example of a barrel tuner was a model 70 Winchester with a boss system, once adjusted it was amazing how much effect it had on group size with factory ammunition
Just bought an EC tuner brake. I’m having it installed now. Can’t wait to try it out. My best 5 shot group from my .308 is .478 with Federal premium 168 BTHP. This video has me really excited to see how much tighter my groups can get.
@@BLUELEADER78 I did a lot of shooting and testing this month. The EC Tuner brake did a fantastic job. I did most of my testing with Federal premium 175 bthp ammo. I did some testing with 168 and was able to tighten the groups down to .365 for a five-shot group. I ran out of 168 and switched to 175 BTHP. Before the EC brake my rifle would shoot the 175 in the 3/4 moa range very consistently. I started firing 2 shot groups at 0 going in increments of 2. At setting 2 they were touching but I continued on all the way back to 0 being 10. Setting 2 and 8 were both touching. 8 was very slightly tighter. I dropped back to 7 and went in half step adjustments. At 7 it had opened up to about 1/2", 7.5 was about the same, skipped 8, 8.5 was almost 1 hole but I could see it was 2 shots. Setting 9 was 1 hole, I couldn't tell through my spotting scope that 2 shots were there. I sent 3 more making it a 5 shot group. Subtracting the .308 for the bullet diameter the group measured .210. Thats a .518 hole with a .308! Wow, factory Remington 700 PSS .308 26" 1:12 twist with a Timney trigger and an EC Tuner brake is shooting factory ammo sub 1/4 moa !! Will it do it every day, probably not but that remains to be seen. I can say that I am a 100 percent believer in the EC Tuner brake.
I bought one, for my 300 BO with a 16"BBL. on a Unitau Precision Upper. it hates boat tail bullets. With 168 gr A Max. Just the break cut the groups in half with no adjustment.
I'm curious about conistancy. Maybe firing 3 groups per setting then averaging them. That way you don't get one crazy good group skewing your conclusions.
Use the tuner brake on my prs 22 br. 95 gr smk, h4350. Last group on paper was measured at .281-.224=.057 for 5 shots. Consistently shoots from .2-.0. Best shooting equipment I've bought!
Years ago I HAD 3 Winchester Boss System rifles, 243, 300 Win, 7mm mag. Each shoot 1/3 MOA. Sold them along the way..... About time someone came out with a Boss style system. I'll buy a few dozen.
Statistics of distribution do not favor barrel tuners. Two 30 shot groups, one without tuner and 1 with the tuner in a “node” could tell us definitively if the tuner works, but I’ve never seen this done.
Yes, I use the EC tuner with a 6.5 PRC currently worthing with a load. The rifle is a new MPA with factory match bullets it shot well 1/2 with the turner .119.
I used the 30 caliber EC Tuner Brake on my 700 Remington CDL 7mm Remington Magnum and the difference was worth every penny spent. Results on my hand loads- three shot groups starting 0.78” we shrunk to 0.19” which essentially was one button hole. Never look back!
One test I would like to see is to take the tuner out several rotations and see what happens if you go from zero to say 30. Is there more than one node that can be found and at what distance might that be?
I inherited a browning ab2 .270 with the boss break on it. After shooting a 3/8” group 4 times, i really wanted to get a boss break for my other rifles, but found out that browning discontinued them. I am very happy to see the EC tuners are basically the same thing and work well. My savage 22-250 is about to be stupid accurate lol.

@@travisweldmaster7815 my uncle in law is an avid hand loader and long range shooter. He recently parted with his 7mm rem mag specifically because he hated having to seat it to the belt instead of the shoulders. He had a 280 rem turned into a 280 ai and loves the thing. I shoot 165 ablr’s out of my 30-06, and it is a mortar as well, but its strictly a hunting rifle, so I don’t shoot it far enough to really care. My .270 has swift scirricos, and they are about used up. I may swap it to ablr’s too, though I’ve heard great things about the eld-m’s, and they are significantly cheaper,
@@fnkdtnkI gotcha, nothing wrong with that, to each his own, I headspace off the shoulder to head like any other, like the belt isnt even there, no problems, but everyone's setup isnt always the same
I've had a stainless Winchester model 70 in 30-06 for over 25 years. It came with the BOSS system...and was apparently way ahead of it's time. It is the same principle as this - a brake with a tuner. It's a shame it was discontinued. I dialed it in for factory 150gr loads when I first got it and it shot 1/2" groups...and it has shot them continuously since then.
Trying to remember- was the BOSS system the one on the end of barrel that you twist to make adjustments? Or was it the one that was a sliding weight on the barrel?
I tuned mine for 168s and has been fantastic for years as well. No need to buy another rifle since. Have about 800 rnds through it now, so there's plenty of life left in it. My buddies that shoot it can't believe that the '06 could be that accurate. It can.
Thanks for a very interesting and practical experiment. Currently there is not a temperamental rifle in my safe, however if I do have issues the EC Tuner will be part of my solution.
literally the cure to accuracy! eric cortina doesn’t play around everything he sells is 100% legit . great prices and the box it comes in is super badass
I have his EC Tuner Break in 308 and 6.5. shot a 3 shot 308 group tuned to #7 on the break.... Hole diameter was .398 on the target. Still working load data for the 6.5. Love the breaks
I have an .30 cal EC T/B on my 6.5 Creedmoor. It is legit. And changing one parameter 100% changes the whole system. I found a setting of 8 worked awesome with my Federal primers. But shot like shit with my CCI primers. CCI settled on a setting of 16. Got just a hair under 1/4 MOA out of a custom load on a FACTORY Tikka Tac A1. Not too shabby.
Would love to see you do the tuner adjustment as shown. Then shoot a 20 shot group with the best and worst settings. Also, as others have said step back through the adjustment a 2nd time and see if you land on the same settings for best and worst groups.
When taking it off and putting it back on i would try and use a crows foot on a torque wrench to make sure the tightness to the muzzle is the same to remove another value from testing.
Really interesting. This subject matter has been of many topics on several LIVE show, using a "barrel tuner or not"... And it really is interesting to see so many other there building a general census for the Pro's & Con's of this. Also worth mentioning, many of these folks that are already going on with this adventure of experimenting with a barrel tuner, of various brands and types, it will be crazy interesting to see the various calibers. Something so simple, yet, exceptionally complicated. These kinda remind me of the sky-scraper tuned dampers. (the multi-ton chunk of steel at the very top of the sky scraper to calm the swaying down), yet, it is just a chunk of heavy mass, hanging from cables, all the while ever so delicately balanced or tuned to the buildings harmonics.. I look forward to trying one in the future. I am a bit away's from trying one just yet, as my skill set is still too messy, to be able to notice a difference, as per, is the P.O.I. me, or the rifle system or weather, etc.... Soon though. that will be fun to play with a few of these various types of anti-harmonic / damper units.. Thank you for showing the graphs, I enjoy that seeing that kinda stuff, it helps my mind understand further what you are saying in a 2D format.. Thank you.
This sounds like the product I may need. I had a load that consistently shot .5” inch groups at 100 yards with single digit ES/SD. Shot a 4” six shot group at 995 yards with that load. Then I ran out of powder and switched to a different lot of the same powder. For reasons I’m still scratching my head trying to figure out why the groups went to crap. I would have three touching and two fliers high and low. However, the velocity node stay the same with single digit ES/SD at the same charge weight. The velocity did drop approximately 50 fps though. I also developed a load for a couple 308 rifles that have BDC reticles, is gas operated and the other is bolt action. The load I’ve developed runs identical ES/SD in both rifle, low teen ES and single digit SD, and the ballistics match the BDC reticle. The bolt gun shoots a consistent .5” five touching group at 100 yards, but the gas gun shoots .8”. I imagine this brake may shrink those gas gun groups down some more.
I just got back from the range. I have the EC..2 tuner break, and it's amazing. I'm getting ready for hunting . I loaded with no load development. I used 40 guns of Varget, under a Berger 175 grn vld hunter. At setting 8 I got.25 inch group at 100. I tried 7 and it opened up to 3/8". I went to 8+ and it shrunk the group to 0.029 ,3 shot group. No load development. I'm good for in the bush where my longest shot will be just over 200 m over a pond.
We have the BOSS on a Model 70 in .270 and another on an A-Bolt Eclipse Varmint in .308, I don't know why they stopped producing them as they really work well.
Yeah,I put a brake on a 25 WSSM AR.IT went from 1/2 “ groups to 1 1/2” or worse.Took the brake off,tightened up.So I have a EC TUNER brake on order .Hopefully it will not let me down
I know this is 3 years old, but EC and others need to thank Winchester / Browning because this is basically the 2020 version of the early 1990's BOSS system. And it worked like a champ back then even though folks said it looked stupid on the end of a barrel.
Winchester BOSS accomplished this...I have this on a Model 70 in 22-250; dime -sized 3 shot groups all day. Happy to hear there is another option out there because Winchester ditched BOSS, years ago.
I think the best strategy to use a tuner is to tune a load for minimum ES and SD, then tune the harmonic to get a small group. When you do an OCW ladder for load development, you are tuning your load to match your harmonics, so if you tune for velocity and then for harmonics, you should be able to optimize both and find the widest node to shoot in.
Yep the BOSS-system: www.browning.com/news/tech-terms/boss-rifle-accuracy-system.html and www.browning.com/support/faq/tune-boss.html Still available on the BAR mk2 Safari apparently
Browning used to have what they called the B.O.S.S. It worked great. I have a Browning Abolt in 270 WSM with a Boss on it and will shoot sub moa all day long, once i got it fine tuned.
its all about harmonics,always has been look at structured barrels if you can find that node its magic, but the ammo has to be consistent as well each round is throwing a frequency range, gotta stick with a load and run with it, you dont need anything fancy either simple washers/weights on the muzzle work
Yeah basically your method would be run a ladder and pick the charge weight that has the smallest standard deviation on velocity. Then load up a bunch of that load. And take the ones you just loaded that are all the same load with your best standard deviation of velocity, and shoot a fire you shot group turn out the turner. Shoot another group. Turn out the tuner. And so on. By the time you've done say 50 rounds there you should have found a couple of nodes that are fairly accurate. You know I don't have to compromise between a harmonic node and a consistent velocity node you can choose both. You adjust your powder to be the consistent velocity and you adjust your barrel to be the consistent harmonic.
@@GunFunZS Thanks. I've been working up a load for my hunting rifle using Barnes 175gr .308 LRX with Superformance powder with CCI250 primer and Winchester brass. I've used Dan Newberry's OCW method and I tried the Saterlee 10-shot ladder test and they both gave me 58.0 gr of Superformance as the sweet spot. I then played with the seating depth, but my riflescope started acting funny and it turned out to be defective. I finally got a new/used Vortex Viper HS-T 4-16x44mm scope 2 days ago so I hope to get back to the range soon and finish the load development. Cheers!
@@onelegwest I'm willing to bet money on two things. 1 you were probably a much better shot than me. 2 The defect of that rifle you rejected was probably more than sufficiently accurate for the hunting you're actually going to do with it. And the third thing that I won't bet on but do suspect is that you will end up with a very accurate load by the time you are done.
YES! Definitely test taking the EC Tuner off of the rifle, messing with the setting and then remount and set back to desired setting. I'd love to see that tested. I'm an Eric Cortina fan because he clears the muddy water stirred up for us who have less knowledge, he backs it up with proof
If you remove the Magnetospeed from the barrel the group size will shrink even more! I've found that it GREATLY influences barrel harmonics which has lead me to the Lab Radar solution!
In one of his videos about seating depth Eric himself says that you can tune "any load" just by adjusting seating depth. IOW, according to him, changing seating depth changes harmonics in a manner similar to a tuner.
I have a 6 ARC 22” bbl in a gas gun, would be very interested in getting a break, like the one you guys tested. My bbl has a 5/8 thread like the 6.5 Grendel has also.
I have a 308 that I hand load for and a 300 PRC that I do not have immediate plans to hand load for due to lack of component availability. My question is do you feel that this brake is potentially a money/ammo saver for dialing in factory loads?
The 'don't neck size' thing was always a scam - Erik only neck sizes. He was just saying that to get everyone NOT to neck size, and give himself a competitive advantage.
I'm curious how ambient temperature would affect tuner results. I suppose if powder burn was exactly the same at any temperature, there would be no affect. It would be interesting to see results on a cool cloudy day versus a hot sunny day. Interesting video. I just put a tuner on a very nice .22 LR so anxious to see how it affects accuracy at 50 yards and beyond.
I'd very much like to know the repeatability. as I have and mostly use a supressor and want to get this for some club matches. the idea of being able to remove and replace without reworking up loads is very appealing so repeatability is key to me wanting it
It sounds like the ECTuner device will help shooters realize the full potential of their rifle. Certainly, there is no easier or less expensive way to experiment with extracting the most out of a group of components, before making more radical changes.
Would love to see this with multiple 5-shot groups per setting (I never use less than 5 for any testing aside from a ocw test) Single groups of 3 shots seem a little light to establish conclusive results-- 3 is not enough to establish a "real" group size IMO. Love the review and discussion-- just need to see more before it would have me feel that this would affect my shooting enough to buy the product, remove my brake, decide to not use a can, etc.
The EC tuner and brake looks nice and light. I've been using the Harrell's Precision tuner brakes for a few years now. I also have two Browning rifles with the older BOSS brakes. One downside of the Harrell's is their weight, so not something to put on a rifle that you want to keep as light as possible. For bench rest shooting, hunting and nuisance varmint hunting, I have seen great results with the Harrell's brakes. However, I have never taken one off and then put it back on for repeatability. I've always installed the brake, tuned it and then locked it in place with judicious application of blue Locktite. I learned to take shooting notes in the US Army, and track my reloading, and shooting so I can tell where the sweet spot is with my loads.
Have one sitting on the shelf right now. Going to try it on my 6mm arc when I finally get the upper. (Of course do a baseline test with original brake first.) Haven't heard of anyone trying them on gas guns. Guess there's only one way to find out.
I may have missed it, but it would be nice to hear if the brake portion of the tuner brake is effective also. I am on the fence now and don't like the brake on my current setup. Keep the great videos coming.
Helpful tip Gavin. It seems Travis is a soft-spoken guy, so you need to turn his microphone up. You are coming in loud and clear, but we can hardly hear Travis. Great Video.

I like your partner’s idea for swapping, taking notes and repeatability.
"The difference between science and screwing around....is writing stuff down"
It really would of made the study that much more reliable. I hope they try this.
I can almost guarantee that if this is taken off and reinstalled, that the tuning will change. I wouldn’t see this as the tuner/brakes’s fault though.
Me too.
I bought a EC Tuner for my Remington 700-7mm REM Mag elk hunting rifle. My results were definitely similar to yours. My three shot groups went from .815 @ 100 yds to .279” @ 100 yds. I did have a setting where my groups opened up to over 1” (1.40”) then back to my best grouping. As a side note I was using IMR-4831 powder and Nosler 160 gr Accubond bullets.
I started reloading this year and I have an EC tuner break on my 300 wm. The best I could get my reloads was a half inch group but by using the EC tuner I’m now shooting 1/4 inch groups. With factory ammo my gun will shoot 1 inch groups but the EC tuner will help me get them under a 1/2 inch groups. My rifle is a Christensen arms ridgeline. I have also changed the stock. With the stock change and the tuner break it kicks less than my 7mm-08. I enjoy watching your videos because you are very informative. Please keep up the good work.
Great idea about taking it off and putting back on to see if results stay true.
What happens when you take your scope off and Remount it? What happens when you secure your stock screws
I had a 6.8 SD but a.67" group. Added the EC-TUNER and got to setting "6"! One fricking hole! 😎
That is exactly what mine did, 6 was a one hole group. 6 Creedmoor.
Yessir, same experience I had...love it!
Bought an EC tunner for my 6.5 cm. My biggest surprise was reduction in recoil. I was surprised it has less recoil than my suppressor ( Gemtech 300 win mag). My last 3 shot group was .218
LOL, well, it is a muzzle brake.
I have the 30cal brake i swap on 6cm 6.5cm and 6.5-300bee. Set to original settings and it stays true. Takes half of the work out of load development. Erik makes an amazing product.
I was wondering if the 30 cal brake would be effective on lower caliber rounds, that is how well it would work to reduce recoil and tune .280 and .270 cal rifles. Sounds like it works on your rifles.

Bought one of these for my .338LM. Worked amazing, love it. Loved it so much I just ordered another one for my 6.5CM. And I can't wait to see how much it changes things on an already great shooting rifle.
Another killer aspect of tuner is if you run data in temp changes and record it, you can tune load in colder/warmer weather. I run a 6.5 Lapua for PRS and it works. Without having 2 different loads.
I dont have one yet. And was wondering if that could be tested. Awesome info.
For those weary of the tuner brake; buy one and install it as if it were a standard brake. Develop a load conventionally with a powder and seating depth node that shoots well. When you go to a match and your groups start opening up because of throat erosion or change in temperature/pressure, you can adjust your tuner on the fly as a backup.
I think this thing can cut your load development time in half. It would be so nice to find a powder charge with low sd and then you could essentially finish your load development in 1 day at the range as opposed to making a bunch of trips back to your reloading bench
Easiest thing to do would be to have a tuner for each rifle. But, I like the repeatability idea for those on a budget and want, or are limited to, that capability. I'm a fan of Erik and have learned a lot from his channel.
He's got a lot going right now and yes I've learned alot from him to very smart man
I picked one up a while ago and it works wonders on my rifles! It saves me a lot of time and money so I don't have to play around with bullet seating depth especially when getting components are hit and miss.
My first example of a barrel tuner was a model 70 Winchester with a boss system, once adjusted it was amazing how much effect it had on group size with factory ammunition
Erik’s tuner works great.
Just bought an EC tuner brake. I’m having it installed now. Can’t wait to try it out. My best 5 shot group from my .308 is .478 with Federal premium 168 BTHP. This video has me really excited to see how much tighter my groups can get.
Have you had a chance to test it?
@@BLUELEADER78 I did a lot of shooting and testing this month. The EC Tuner brake did a fantastic job. I did most of my testing with Federal premium 175 bthp ammo. I did some testing with 168 and was able to tighten the groups down to .365 for a five-shot group. I ran out of 168 and switched to 175 BTHP. Before the EC brake my rifle would shoot the 175 in the 3/4 moa range very consistently. I started firing 2 shot groups at 0 going in increments of 2. At setting 2 they were touching but I continued on all the way back to 0 being 10. Setting 2 and 8 were both touching. 8 was very slightly tighter. I dropped back to 7 and went in half step adjustments. At 7 it had opened up to about 1/2", 7.5 was about the same, skipped 8, 8.5 was almost 1 hole but I could see it was 2 shots. Setting 9 was 1 hole, I couldn't tell through my spotting scope that 2 shots were there. I sent 3 more making it a 5 shot group. Subtracting the .308 for the bullet diameter the group measured .210. Thats a .518 hole with a .308! Wow, factory Remington 700 PSS .308 26" 1:12 twist with a Timney trigger and an EC Tuner brake is shooting factory ammo sub 1/4 moa !! Will it do it every day, probably not but that remains to be seen. I can say that I am a 100 percent believer in the EC Tuner brake.
I bought one, for my 300 BO with a 16"BBL. on a Unitau Precision Upper. it hates boat tail bullets. With 168 gr A Max. Just the break cut the groups in half with no adjustment.
I'm curious about conistancy. Maybe firing 3 groups per setting then averaging them. That way you don't get one crazy good group skewing your conclusions.
Use the tuner brake on my prs 22 br. 95 gr smk, h4350. Last group on paper was measured at .281-.224=.057 for 5 shots. Consistently shoots from .2-.0. Best shooting equipment I've bought!
Years ago I HAD 3 Winchester Boss System rifles, 243, 300 Win, 7mm mag. Each shoot 1/3 MOA. Sold them along the way..... About time someone came out with a Boss style system. I'll buy a few dozen.
I would be interested in seeing the additional three or five-shot groups to see if the results are actually consistent and remain improved over time.
Bingo.
Also wonder if it's repeatable. Could you get it dialed, go back a bit, end on your number, and have the same POI / Group.
Statistics of distribution do not favor barrel tuners. Two 30 shot groups, one without tuner and 1 with the tuner in a “node” could tell us definitively if the tuner works, but I’ve never seen this done.
Yes, I use the EC tuner with a 6.5 PRC currently worthing with a load. The rifle is a new MPA with factory match bullets it shot well 1/2 with the turner .119.
Have a 7PRC will be installing a EC tuner brake!...I will send you my results when I have them...Good stuff guys thank you
Would love to hear a follow up regarding removing it and demonstrating repeatability!
Yes area 419 hellfire self timing muzzle system groups are a lot tighter shooting 338 300 grain bullet can't wait push this out pass a mile.
I used the 30 caliber EC Tuner Brake on my 700 Remington CDL 7mm Remington Magnum and the difference was worth every penny spent. Results on my hand loads- three shot groups starting 0.78” we shrunk to 0.19” which essentially was one button hole. Never look back!
One test I would like to see is to take the tuner out several rotations and see what happens if you go from zero to say 30. Is there more than one node that can be found and at what distance might that be?
Go to Erik’s site, he shows it. There will be several nodes found on running it out from zero.
I inherited a browning ab2 .270 with the boss break on it. After shooting a 3/8” group 4 times, i really wanted to get a boss break for my other rifles, but found out that browning discontinued them. I am very happy to see the EC tuners are basically the same thing and work well. My savage 22-250 is about to be stupid accurate lol.
270 stomps ass, especially when loaded right, to it's full potential, absolute favorite all round cartridge, then the 7rm mg, ballistics are impeccable
@@travisweldmaster7815 I want to add a 7mm someday, but since I handload my rifles, I may get crazy and go 7 SAUM. Why it hasn’t caught on commercially despite being an F class King is a complete mystery to me.

@@travisweldmaster7815 my uncle in law is an avid hand loader and long range shooter. He recently parted with his 7mm rem mag specifically because he hated having to seat it to the belt instead of the shoulders. He had a 280 rem turned into a 280 ai and loves the thing.
I shoot 165 ablr’s out of my 30-06, and it is a mortar as well, but its strictly a hunting rifle, so I don’t shoot it far enough to really care. My .270 has swift scirricos, and they are about used up. I may swap it to ablr’s too, though I’ve heard great things about the eld-m’s, and they are significantly cheaper,
@@fnkdtnkI gotcha, nothing wrong with that, to each his own, I headspace off the shoulder to head like any other, like the belt isnt even there, no problems, but everyone's setup isnt always the same
I've had a stainless Winchester model 70 in 30-06 for over 25 years. It came with the BOSS system...and was apparently way ahead of it's time. It is the same principle as this - a brake with a tuner. It's a shame it was discontinued. I dialed it in for factory 150gr loads when I first got it and it shot 1/2" groups...and it has shot them continuously since then.
Trying to remember- was the BOSS system the one on the end of barrel that you twist to make adjustments? Or was it the one that was a sliding weight on the barrel?
@@madman432000 It was at the end of the barrel...very similar to the EC system.
I tuned mine for 168s and has been fantastic for years as well. No need to buy another rifle since. Have about 800 rnds through it now, so there's plenty of life left in it. My buddies that shoot it can't believe that the '06 could be that accurate. It can.
I didn’t know Winchester had the boss system I have only seen it on brownings I thought it was special to them.
@@dbuckner902010 Winchester and Browning are both owned by the same.
you really need to confirm those results with more than a single group
Yeah a 3 shot group only gives a 20% confidence interval for being within standard deviation interval.
I have an EC TUNER PN A 40 cal muzzleloader. It truly does make a difference!
Thanks for a very interesting and practical experiment. Currently there is not a temperamental rifle in my safe, however if I do have issues the EC Tuner will be part of my solution.
Gavin the EC TB works very well
literally the cure to accuracy! eric cortina doesn’t play around everything he sells is 100% legit . great prices and the box it comes in is super badass
What is the cost of this tuner/ brake ?
Good series with the two guys 👍 Gavin get's help from Travis 😁
I have his EC Tuner Break in 308 and 6.5. shot a 3 shot 308 group tuned to #7 on the break.... Hole diameter was .398 on the target. Still working load data for the 6.5. Love the breaks
Respectfully, changes in 3 shot group sizes between one adjustment to another does not seem statistically significant.
I have an .30 cal EC T/B on my 6.5 Creedmoor. It is legit. And changing one parameter 100% changes the whole system. I found a setting of 8 worked awesome with my Federal primers. But shot like shit with my CCI primers. CCI settled on a setting of 16. Got just a hair under 1/4 MOA out of a custom load on a FACTORY Tikka Tac A1. Not too shabby.
I have a EC tuner on my Vudoo. So worth the money.
Good video and information. Been thinking about getting a tuner.
i like to see if it is repeatable and accurate every time you take it off and back on the rifle..... great vid you guys!
Would love to see you do the tuner adjustment as shown. Then shoot a 20 shot group with the best and worst settings. Also, as others have said step back through the adjustment a 2nd time and see if you land on the same settings for best and worst groups.
When taking it off and putting it back on i would try and use a crows foot on a torque wrench to make sure the tightness to the muzzle is the same to remove another value from testing.
Bingo! Any ideas on how to ensure consistent timing?
Really interesting. This subject matter has been of many topics on several LIVE show, using a "barrel tuner or not"... And it really is interesting to see so many other there building a general census for the Pro's & Con's of this. Also worth mentioning, many of these folks that are already going on with this adventure of experimenting with a barrel tuner, of various brands and types, it will be crazy interesting to see the various calibers. Something so simple, yet, exceptionally complicated. These kinda remind me of the sky-scraper tuned dampers. (the multi-ton chunk of steel at the very top of the sky scraper to calm the swaying down), yet, it is just a chunk of heavy mass, hanging from cables, all the while ever so delicately balanced or tuned to the buildings harmonics.. I look forward to trying one in the future. I am a bit away's from trying one just yet, as my skill set is still too messy, to be able to notice a difference, as per, is the P.O.I. me, or the rifle system or weather, etc.... Soon though. that will be fun to play with a few of these various types of anti-harmonic / damper units.. Thank you for showing the graphs, I enjoy that seeing that kinda stuff, it helps my mind understand further what you are saying in a 2D format.. Thank you.
My buddy has a tuner on his 37xc as well as a terminator muzzle brake! They absolutely positively do work , I’ve seen it first hand…
very cool product. unfortunately, my tuner is a suppressor. it only has 2 settings: on and off... i prefer the "on" option!
I had great success with the predecessor Browning BOSS on rifles in past. I often wonder why Browning quit offering the BOSS?
This sounds like the product I may need. I had a load that consistently shot .5” inch groups at 100 yards with single digit ES/SD. Shot a 4” six shot group at 995 yards with that load. Then I ran out of powder and switched to a different lot of the same powder. For reasons I’m still scratching my head trying to figure out why the groups went to crap. I would have three touching and two fliers high and low. However, the velocity node stay the same with single digit ES/SD at the same charge weight. The velocity did drop approximately 50 fps though.
I also developed a load for a couple 308 rifles that have BDC reticles, is gas operated and the other is bolt action. The load I’ve developed runs identical ES/SD in both rifle, low teen ES and single digit SD, and the ballistics match the BDC reticle. The bolt gun shoots a consistent .5” five touching group at 100 yards, but the gas gun shoots .8”. I imagine this brake may shrink those gas gun groups down some more.
I just got back from the range. I have the EC..2 tuner break, and it's amazing. I'm getting ready for hunting .
I loaded with no load development. I used 40 guns of Varget, under a Berger 175 grn vld hunter.
At setting 8 I got.25 inch group at 100.
I tried 7 and it opened up to 3/8".
I went to 8+ and it shrunk the group to 0.029 ,3 shot group. No load development.
I'm good for in the bush where my longest shot will be just over 200 m over a pond.
Remember the boss system on Browning and Winchester rifles in the 90s it too was adjustable
I had a 22-250 with the Boss and within 20 rounds I had less then a 1/2 inch group at 200 yards. If this is even close I want one
I still have my model 70 sporter boss in 3006
We have the BOSS on a Model 70 in .270 and another on an A-Bolt Eclipse Varmint in .308, I don't know why they stopped producing them as they really work well.
Yeah,I put a brake on a 25 WSSM AR.IT went from 1/2 “ groups to 1 1/2” or worse.Took the brake off,tightened up.So I have a EC TUNER brake on order .Hopefully it will not let me down
I know this is 3 years old, but EC and others need to thank Winchester / Browning because this is basically the 2020 version of the early 1990's BOSS system. And it worked like a champ back then even though folks said it looked stupid on the end of a barrel.
Winchester BOSS accomplished this...I have this on a Model 70 in 22-250; dime -sized 3 shot groups all day. Happy to hear there is another option out there because Winchester ditched BOSS, years ago.
I have 2 a 6.5 creed and a .308.
THESE WORK!.
I think the best strategy to use a tuner is to tune a load for minimum ES and SD, then tune the harmonic to get a small group.
When you do an OCW ladder for load development, you are tuning your load to match your harmonics, so if you tune for velocity and then for harmonics, you should be able to optimize both and find the widest node to shoot in.
100%! That is something we talked about in the vid.
Very interesting. I remember Browning came out with a similar setup in 80s or early 90s I think.
Yep the BOSS-system: www.browning.com/news/tech-terms/boss-rifle-accuracy-system.html and www.browning.com/support/faq/tune-boss.html
Still available on the BAR mk2 Safari apparently
@@gusmodelmaker YES!! That was it.
I was wondering if this was different. But except for the muzzle break I guess not. Cool piece of gear for sure.
Tuners can help shot placement. small caliber rifles can use improvements on shot placement. It really helps when hunting, large or small game
I watch Erik Corrina's UA-cam channel. He's really funny. Plus, he has a lot of good advice for people who want to get into accurate rifles.
Browning used to have what they called the B.O.S.S. It worked great. I have a Browning Abolt in 270 WSM with a Boss on it and will shoot sub moa all day long, once i got it fine tuned.
This is the same concept as the BOSS system on the Win 70 and The Browning rifles. It works!
its all about harmonics,always has been look at structured barrels if you can find that node its magic, but the ammo has to be consistent as well each round is throwing a frequency range, gotta stick with a load and run with it, you dont need anything fancy either simple washers/weights on the muzzle work
I knew I should of got on the black tuner list few months ago. Load work is done and want to see if I can get into 0.1
The browning Boss is just like the break. I have it on my a bolt 2 medallion 280 rem. It really works
Great video. So... With the EC tuner, a person could develop a very fast load and then use the EC tuner to tighten the groups. Correct?
Yeah basically your method would be run a ladder and pick the charge weight that has the smallest standard deviation on velocity. Then load up a bunch of that load. And take the ones you just loaded that are all the same load with your best standard deviation of velocity, and shoot a fire you shot group turn out the turner. Shoot another group. Turn out the tuner. And so on. By the time you've done say 50 rounds there you should have found a couple of nodes that are fairly accurate. You know I don't have to compromise between a harmonic node and a consistent velocity node you can choose both. You adjust your powder to be the consistent velocity and you adjust your barrel to be the consistent harmonic.
@@GunFunZS Thanks. I've been working up a load for my hunting rifle using Barnes 175gr .308 LRX with Superformance powder with CCI250 primer and Winchester brass. I've used Dan Newberry's OCW method and I tried the Saterlee 10-shot ladder test and they both gave me 58.0 gr of Superformance as the sweet spot. I then played with the seating depth, but my riflescope started acting funny and it turned out to be defective. I finally got a new/used Vortex Viper HS-T 4-16x44mm scope 2 days ago so I hope to get back to the range soon and finish the load development. Cheers!
@@onelegwest I'm willing to bet money on two things. 1 you were probably a much better shot than me. 2 The defect of that rifle you rejected was probably more than sufficiently accurate for the hunting you're actually going to do with it.
And the third thing that I won't bet on but do suspect is that you will end up with a very accurate load by the time you are done.
The EC tuner is a great product. Need to try the. 30 can version.
it’s a great product man . i work for eric in his shop everything he sells is great .
@@cedricmendoza1305I just tried to buy one the website states out of stock , will these soon be available again ?
Erik’s advice is to look for two small groups in a row when testing the brake.
Gotta get one.Been waiting on EC to get his new Mill all lined out
YES! Definitely test taking the EC Tuner off of the rifle, messing with the setting and then remount and set back to desired setting. I'd love to see that tested. I'm an Eric Cortina fan because he clears the muddy water stirred up for us who have less knowledge, he backs it up with proof
If you remove the Magnetospeed from the barrel the group size will shrink even more! I've found that it GREATLY influences barrel harmonics which has lead me to the Lab Radar solution!
Exactly. Always wondered why people shoot for groups with the magnetospeed on the barrel. You are effecting harmonics of the barrel.
We did not shoot the final test groups with the Magnetospeed on. We did test with it on as the video shows. The results are all from the tuner.
@@Tfox31 this is exactly what I do. I use the Magneto for velocity mode testing...then you shoot groups to adjust bullet seating.
In one of his videos about seating depth Eric himself says that you can tune "any load" just by adjusting seating depth. IOW, according to him, changing seating depth changes harmonics in a manner similar to a tuner.
I have a 6 ARC 22” bbl in a gas gun, would be very interested in getting a break, like the one you guys tested. My bbl has a 5/8 thread like the 6.5 Grendel has also.
I have the same setup as you and just got the EC tuner brake but haven't tried it yet.
I have a 308 that I hand load for and a 300 PRC that I do not have immediate plans to hand load for due to lack of component availability.
My question is do you feel that this brake is potentially a money/ammo saver for dialing in factory loads?
I hear Erik is still neck sizing! 😆
Don't say that!!!! :) :)
He is going to randomly show up at the range behind you and smack you up side the head lol
The 'don't neck size' thing was always a scam - Erik only neck sizes.
He was just saying that to get everyone NOT to neck size, and give himself a competitive advantage.
one of the best shooters in the world man
@@2whl4re well there's a wild story 🤦♀️
I'm curious how ambient temperature would affect tuner results. I suppose if powder burn was exactly the same at any temperature, there would be no affect. It would be interesting to see results on a cool cloudy day versus a hot sunny day. Interesting video. I just put a tuner on a very nice .22 LR so anxious to see how it affects accuracy at 50 yards and beyond.
Well what happened?
I'd very much like to know the repeatability. as I have and mostly use a supressor and want to get this for some club matches. the idea of being able to remove and replace without reworking up loads is very appealing so repeatability is key to me wanting it
Yeah... I think I'll trust the testing by Bryan Litz and Hornady that shows they do zip, nada, zilch, nothing. Small sample sizes are meaningless.
It sounds like the ECTuner device will help shooters realize the full potential of their rifle. Certainly, there is no easier or less expensive way to experiment with extracting the most out of a group of components, before making more radical changes.
Would love to see this with multiple 5-shot groups per setting (I never use less than 5 for any testing aside from a ocw test) Single groups of 3 shots seem a little light to establish conclusive results-- 3 is not enough to establish a "real" group size IMO.
Love the review and discussion-- just need to see more before it would have me feel that this would affect my shooting enough to buy the product, remove my brake, decide to not use a can, etc.
You just got a new subscriber mate!
The EC tuner and brake looks nice and light. I've been using the Harrell's Precision tuner brakes for a few years now. I also have two Browning rifles with the older BOSS brakes. One downside of the Harrell's is their weight, so not something to put on a rifle that you want to keep as light as possible. For bench rest shooting, hunting and nuisance varmint hunting, I have seen great results with the Harrell's brakes. However, I have never taken one off and then put it back on for repeatability. I've always installed the brake, tuned it and then locked it in place with judicious application of blue Locktite. I learned to take shooting notes in the US Army, and track my reloading, and shooting so I can tell where the sweet spot is with my loads.
you definitely need to try it out the Ec brake is great
I've got a ruger mk77 all weather 7mm rem mag I had a BOSS brake put on it back in the late 80's I still love it
Have one sitting on the shelf right now. Going to try it on my 6mm arc when I finally get the upper. (Of course do a baseline test with original brake first.) Haven't heard of anyone trying them on gas guns. Guess there's only one way to find out.
Yes, tuners work. HOWEVER... you need to use a chrono to ensure a small ES and SD in your projectiles.
I may have missed it, but it would be nice to hear if the brake portion of the tuner brake is effective also. I am on the fence now and don't like the brake on my current setup. Keep the great videos coming.
My feeling is as a brake it is very good.
That is the constant with shooting. Working so dam hard to find a group and have a single determining factor that can blow You out of the water.
I owned a Browning A bolt in 300 win magvwith the Boss system. It was awesome!
I'm liking it definitely going to be picking one up soon!!!
Helpful tip Gavin. It seems Travis is a soft-spoken guy, so you need to turn his microphone up. You are coming in loud and clear, but we can hardly hear Travis. Great Video.
