Glad your back...I was going through JRB withdrawals. Sorry to hear about the plum damage. The good never stays good, and the bad never stays bad. Love these long vids. Thanks for all your hard work!
Hey JRB, I know this is a yr or 2 old video, but still wanted to say thank you for, one; all your videos and two; I especially respect that you post vids where things worked out not so great. Ive been a long time viewer, and I can safely say that Ive learned a crap load from you and thats a big reason why I watch. So these videos are very helpful in that way! Im writing this as your hitting your 6-7mo mark on twitch now too and while some may not appreciate that new format, or the vids where results arent optimal, Im pretty sure youve got a large following that does appreciate it, so keep it up and thanks man! Btw, just saw, somehow for the first time, your Elite Tactical Warfighter skit. Brilliant man
This video was awesome. So educational. Really enjoyed it. Sir I really thank you for the time you took, and all your efforts and expense to teach. Fantastic documentary on reloading.
Ive just found your channel. I have been reloading since about 1990. I've learned that you CAN teach an old dog new tricks. Like the channel bud...keep the videos coming 👍
Man, I gotta say, your channel and your ability to teach through it has been absolutely amazing.. I began reloading roughly 6 months ago and I find myself going through your vids almost everyday, some I’ve watched multiple times..I’ve learned A TON of great info! Gotta say THANK YOU! Wanted to recommend to maybe look at the Honey Badger barrel by Q. It’s a 7”, 1:5 twist! Has a very unique gas block that is installed with a screw on nut! I have one, and because of the fast twist it stabilizes subs like no other!! Just a suggestion as it might help you as you try more of these types of problematic bullets for 300blk.. Keep up the great work!!!
Something learned is never a bad day at the bench & range! Unfortunate that they didn't stabilize but that lesson is part of learning each of our barrels. Thank you for uploading this and praying things improve. Getting kicked around by life is never what we want.
Love your methodology. Sometimes epic failures make the best movies! Sharing your struggles saves all of us from having to do it ourselves. I’ve been reloading 300 BLK subsonic since it first hit the market and before it was easy to get. Didn’t even watch UA-cam back then, but man your videos sure would have helped. Hope you have a better week!
Didn't think you were ever getting back to 300 blkout. Glad to see it. I love reloading and playing with the subsonic 300 blk. Thanks for bringing it back.
You are wrong Johnny! This is a great, instructive video! There is a tremendous amount of knowledge to be gained here. Thomas Edison was once asked " What is the definition of success"? He replied: "Success is 99% failure!" Your video spoke volumes about your intelligence. I envy you.
I am putting together a 300 blk out ar. 10.5 PA barrel. And I was planning on buying CFE Black The whole intent is a suppressed tractor gun for groundhogs/woodchucks. Your frustration may have saved me some. I watched the whole video and still enjoyed it. TY for what you do. May your channel continue to grow, it is my no 1 reloading channel to come to.
When life kick you in the plums, you make prune juice... That being said your videos convinced me to take the reloading plunge and always look forward to new content!
I had no problem getting this bullet to stabilize at subsonic velocities out of a 16.25 in 1 out of a 7 twist Thompson Center barrel. Getting them to expand was a different story.
These videos are great and so informative. I learn a lot. Have you thought about testing a 1-in-5 twist barrel to test stability of heavier (220gr+) bullets? I’d love to see a comparison of twist rates with your methodical approach and reloading acumen.
I was doing some research on these a couple of months ago. Some things that people that were having success did was use a 30 carbine seating die, 11.2gn max with blk, and 10.5gn max with H110. One person on Midway said their muzzle brake caused issues and had to use a flash hider.
Should color the projectile with sharpie to keep eye on back out..on the Mac cart length... I've noticed few Ive done have caught the rifling and backed out... Can't find funds to buy the gauge...
I wonder why the gates twist barrel I could find when I put my .300bk together was 1/7 when it was designed by AAC as a 1/5. That seems like the ticket to stabilize the 220gr. Bullets
That live round extraction was a "Nail Biter"! Large projectile instability may be caused by the round not being loaded concentric. The Ogive is long and round so however the bullet starts the lands, it finishes that way. The point only 1mm off will cause an imbalance that turn the bullet into a corkscrew. It may be better to order seating cones specifically for the Big Boys. At their per unit cost, it would be worth it.
Mr Johnny, Documented failure is still potential knowledge. Thank you for all the work you put into these videos. I appreciate it. I would like to propose an idea for a video. I'm not being smart or creative or trying to prove any point. I am honestly curious about the idea of a "brush gun" being more well suited to shoot through light brush cover with little effect on accuracy. I would love to see a test comparing a high velocity smaller diameter projectile verses a lower velocity larger diameter heavier projectile going through light woodland cover. 100 yards, baseline group, then light brush cover interference for each type at 20, 40, 60, 80 yards. I personally think that if a game target's vital area is obscured by enough foliage or brush to possibly interfere with the path of the projectile, it isn't a clear shot. Meaning that I think any rifle bullet can bust through a few twigs. If there are enough twigs to interfere with a bullet, there isn't clear enough visibility to positively identify the target. Thanks, Johnny!
You need to do like a "conclusions" or "lessons learned so far" every now and again for specific calibers, to review things you've done in the past, and where you plan on going next. I'm personally looking at going for a 300blk in an 8 or 9" barrel, but mainly want to go subsonic with very heavy 210/220/230gr bullets. Have you tried the Lee 230gr's cast, in a subsonic pistol yet? I'd be OK with 2-3 MOA, as I doubt i'd take it beyond 200 maybe 300 yards (and probably with supersonics at those ranges)
When you put out a new video, it’s always a good mental health, rehabilitation type of day:) Thanks for always putting out great content that always entertains! Hopefully life stops kicking you in the plums:) we love you man!:)
I’ve got some 220 ballistic tips from SSA I’ve been shooting through my gun. I’ll have to put them on paper now and look for keyholing. I never thought it would be an issue with this bullet since it’s shorter than the 220 bthp the round was built around
You know, in Load Development there is a lot of Science, and a lot of Personal Perseverance, a lot of Research, and a dose of Luck does not hurt either. My own personal demon is a 7mm Weatherby that will put 3 bullets in one hole and 2 more 3 to 4 inches away in random areas. I might need a Preist for that one.................LOL
Johnny, I just finished up playing with these, I found a 2.110 oal with a 1-8 twist worked in my 10.5 inch ar and my 16.25 MGM contender with 11.5 of cfeblk worked great. In the 1-7 twist RARR it was yawing everytime. Oh well it works in 2 out of 3 tested.
Wow! I look back at this 2019 video (Knowing what 2020 will be) and hear Johnny talking about "Life has been kicking me right in the plumbs lately" OH! Johnny, if you only knew then what 2020 was going to be like. . . . . you would have enjoyed those crappy days in 2019 like they were golden times.
Great details... Try doing the test over without the suppressor, before testing with the suppressor to see if the grouping is tighter and velocity closer with or without the suppressor.
A little off topic but I was working up a hunting load for my 16" 300 blackout and came across some data that shocked me. I tested it out and have found it to be true. Nosler 125 grain ballistic tip can be pushed to 2400 fps without pressure issues what so ever. Would love to see you test it out in yours to compare some results
Hmm, running s 10.5 inch barrel, 2.10 OAL LC brass, Winchester SR, primer 11gr CFE black 1054 avg velocity, and stable. I use these between 4750-7000 feet elevation above sea level. Works great in the 16 inch bolt gun as well. BTW they are 1/8 and 1/7 twist respectively. I have learned a lot from your vids and appreciate the knowledge you share. Keep them rolling.
I'm in CO and I load mine for around 925-975 fps to make up for altitude, temps, and humidity. Silence is golden. Glad to see you taking some time out for us.
I use the sierra nr 2180 (220g round nose) with 7 grain Vectan AO. I get allways about 1000fts. perfect group untill 80yards. I thought you had them too. Happy your back, i got tiered from Scotty Kilmer
After watching you for a year or two, I'd say that it's time to build a shooting shack, gazebo, ramada... what ever you want to call it. Will keep you out of the sun, rain, snow etc.
thank you for the video .I am going to build me an Ar style rifle and now I am sure if I decide on the 300 BO it will have a 16 inch barrel .thanks for the info
Hey Johnny, love your videos and all the data that you create in them. If I could make a suggestion without knowing anything about your audio/video processing software, I would recommend putting on a mild compressor and high frequency limiter for the viewers pleasure. It prevents the gunshots from being way louder than the rest of the video by using a compressor and the frequency limiter (high pass filter) prevents certain noises from having a sharp hiss to them. It's super easy to set up and I'd be more than happy to talk more about it with you.
Hey Johnny, Hope the plum softening exercise is complete. Looking forward to seeing a notification of a new video from ya. I’ve been reduced to watching LabRadar promotional videos!
Thanks for another good video! Despite the NBT failing, it was informative and enjoyable. Have you considered trying 277 Wolverine? Also, have you considered trying some Shooters World powders (Blackout or Socom-SBR)? They're supposedly really good for both the 300BLK and 277WLV, but I haven't had opportunity to try it in either caliber yet. Thanks again
Start off by saying I love your videos. I'm a subscriber. I've been following this 300 thread all the way through as I am considering a blk build. But with all the troubles you've had with heavy subs, it's got me wondering if it's even worth the hassle. I would want to run heavy subs for self defense and therefore want acceptible short range accuracy and dependable expansion. Did I miss a video? Did I just forget after watching all of them? Or is this round just not worth the trouble?
I just bought two different powders.... That are recommended for Budget. So I'm gonna work on a SUB with TITEGROUP and a SUPER with Lilgun Flavors are 130 gr, 150fmj, 168gr partition, 150gr SP. Small rifle & small rifle MAG snappers.
Round performance was disappointing, but hopefully they get better with possibly more testing. Probably know more then me but i would put a couple more rounds of regular supersonic rounds through that barrel as well, it being so new. I like to break in brand new barrels, and i tend to get better performance out of them when i get at minimum a couple 100 rounds through them.
johnny, I have had no stability issues with this bullet. I am running a 10.3" daniel defense barrel with aa1680 and a c.o.a.l. of 2.100". I think your poor expansion was due to the bullets impacting the gel at an angle(you can see the angle on the ends of your bullets). I shot mine into milk jugs full of water and they acted like varmint bullets-complete fragmentation. They didn't mushroom and stay together at all, there were just tiny bits of lead and jacket pieces throughout the jugs. I would definitely explore it further. since you can shoot on your own property, I suggest maybe just prepping your brass, load 2 or 3 rounds and test stability, then go make adjustments-load two or three more, and test again vs. loading a large batch and finding out it's unstable-this is how i develop subsonic loads to save components. by the way, so glad to see you getting the blackout back in the mix, was getting really bored with all of the 6.5 and 308 videos hopefully you'll get back into the blackout
Accuracy is good with 220 grain Subsonic Ballistic Tip" T/C Encore (1in 7 twist)barrel , under a inch with perfectly round bullet holes at 100 yards. Expansion sucked ,but did use one to kill a whitetail buck, velocity 1050ish FPS, 40 yard shot, next to no expansion, bullet tumbled exit was the exact length as the bullet is long.
Lube has dimension. 0.002 is preferred in engines. If a one thousandth thick layer can support thousands of pounds of force, then it can probably affect your sizing.
Even a bad JRB video is a good video!
We've missed you buddy! Hope things get back in a groove for you.
Glad your back...I was going through JRB withdrawals. Sorry to hear about the plum damage. The good never stays good, and the bad never stays bad.
Love these long vids. Thanks for all your hard work!
Hey JRB,
I know this is a yr or 2 old video, but still wanted to say thank you for, one; all your videos and two; I especially respect that you post vids where things worked out not so great.
Ive been a long time viewer, and I can safely say that Ive learned a crap load from you and thats a big reason why I watch. So these videos are very helpful in that way!

Btw, just saw, somehow for the first time, your Elite Tactical Warfighter skit. Brilliant man
Absolutely love your videos!! Learned so much especially black out videos! Thank you for another one!
Absolutely whole heartedly Second That!
This video was awesome. So educational. Really enjoyed it. Sir I really thank you for the time you took, and all your efforts and expense to teach. Fantastic documentary on reloading.
You shouldn't apologize, this video was worth every minute.
Ironic I’ve been going through your 300blk out playlist during your absence toying with trying this caliber. Best channel on UA-cam here!
Ive just found your channel. I have been reloading since about 1990. I've learned that you CAN teach an old dog new tricks. Like the channel bud...keep the videos coming 👍
Glad to see a video, good result or bad.
Glad to see you back at it with the videos, no matter what the outcome.
Man, I gotta say, your channel and your ability to teach through it has been absolutely amazing.. I began reloading roughly 6 months ago and I find myself going through your vids almost everyday, some I’ve watched multiple times..I’ve learned A TON of great info! Gotta say THANK YOU!

SVTboyy I’d lend JRB my honey badger-barreled upper to test. Would even send bullets, too. It would be an honor.
Something learned is never a bad day at the bench & range! Unfortunate that they didn't stabilize but that lesson is part of learning each of our barrels. Thank you for uploading this and praying things improve. Getting kicked around by life is never what we want.

Oh how I've missed your videos the last few weeks... You sir are funny, entertaining, and informational!
You are wrong Johnny! This is a great, instructive video! There is a tremendous amount of knowledge to be gained here. Thomas Edison was once asked " What is the definition of success"? He replied: "Success is 99% failure!" Your video spoke volumes about your intelligence. I envy you.

I liked your ending. Agree, it should been the beginning AND the end! Thanks for saving me from wasting even a dime on those BT Subsonic projectiles!
Yes! Back to the caliber that started it all, thanks!!!
Just getting to shooting here in Canada. Found ya channel can’t be more happy about how knowledgeable you are about the craft. Funny af too
Thank you for confirming problems with lee dies been having major problems with my Grendel not fully chambering
I was just reading about these on Midway USA and in the comments a lot of people had the same issues.
Well glad to have you back regardless! Man we missed the bench dude!
When life kick you in the plums, you make prune juice... That being said your videos convinced me to take the reloading plunge and always look forward to new content!

😂 your opening comment was exactly what have always been curious about with these bullets
The results were not good, but the video was. I enjoy your longer videos.
Those Nosler 220s are absolutely a baffle strike waiting to happen. All shot sideways out of my Blackout.
Should color the projectile with sharpie to keep eye on back out..on the Mac cart length... I've noticed few Ive done have caught the rifling and backed out... Can't find funds to buy the gauge...
I wonder why the gates twist barrel I could find when I put my .300bk together was 1/7 when it was designed by AAC as a 1/5. That seems like the ticket to stabilize the 220gr. Bullets
Several manufacturers are doing 1/5 twist barrels now.
That live round extraction was a "Nail Biter"!
Large projectile instability may be caused by the round not being loaded concentric. The Ogive is long and round so however the bullet starts the lands, it finishes that way. The point only 1mm off will cause an imbalance that turn the bullet into a corkscrew. It may be better to order seating cones specifically for the Big Boys. At their per unit cost, it would be worth it.
I've been really happy with 115-125 gr bullets in 300 blackout. We missed you!
LOL, never failure on a JRB video, glad to see more fun!
They don't start going sideways before at least 35 to 40 yds. so you have nothing to worry about shooting suppressed.
Love the 300. Keep er coming!
Never apologize for being determined. Nice work. Keep up the good fight brother
Mr Johnny,
Documented failure is still potential knowledge.

Great video. I learned a lot and certainly don’t consider this video a failure!
Missed ya videos man. A day with your reloading vids makes a bad day into a good day
Looks like a rifling twist rate issue for that barrel / bullet length combination. The bullet needs a faster twist rate to stabilize.
Thanks for new content man! I will tune in to any video you make!
When you put out a new video, it’s always a good mental health, rehabilitation type of day:) Thanks for always putting out great content that always entertains! Hopefully life stops kicking you in the plums:) we love you man!:)
Glad your back johnny
Good to see you back jrb.
Time to bring out the ppc😀
I like these longer videos with gel testing. makes for a more complete bullet, load testing.
I’ve got some 220 ballistic tips from SSA I’ve been shooting through my gun. I’ll have to put them on paper now and look for keyholing. I never thought it would be an issue with this bullet since it’s shorter than the 220 bthp the round was built around

My own personal demon is a 7mm Weatherby that will put 3 bullets in one hole and 2 more 3 to 4 inches away in random areas.
I might need a Preist for that one.................LOL
You happen to still have that Weatherby 7mm Mag? I have a bunch of brass for that caliber, but can't find anyone who shoots it.
Johnny, I just finished up playing with these, I found a 2.110 oal with a 1-8 twist worked in my 10.5 inch ar and my 16.25 MGM contender with 11.5 of cfeblk worked great. In the 1-7 twist RARR it was yawing everytime. Oh well it works in 2 out of 3 tested.
This is what is great about your work, if it sucks sat it sucks not personal just business. I hope things are improving for you my friend.
Wow! I look back at this 2019 video (Knowing what 2020 will be) and hear Johnny talking about "Life has been kicking me right in the plumbs lately" OH! Johnny, if you only knew then what 2020 was going to be like. . . . . you would have enjoyed those crappy days in 2019 like they were golden times.
I really enjoy watching your videos. Keep up the good fight.
I'm watching this as I have my first ever cast bullets (150 gr 7.62x39) backing with Harbor Freight flat black in the toaster oven.
Just glad you're back
I have a Bear creek SS 7.5 inch and it 1 in 7 twist. Shoots pretty darn good. It's a $40 barrel to! LOL
too
No rest for the wicked bro. No rest for the wicked 😇 we all have those trying times. I'm glad it got better for you
I have the same barrel and used the same powder, bullets and charge weights. Had same results too. I have a few hundred of these bullets for sale.
Great details... Try doing the test over without the suppressor, before testing with the suppressor to see if the grouping is tighter and velocity closer with or without the suppressor.

Hope the plums have a easier time of it. YEAH for returning to 300BLK!
Good to see ya back brother!
I'm in CO and I load mine for around 925-975 fps to make up for altitude, temps, and humidity. Silence is golden.
Glad to see you taking some time out for us.
I use the sierra nr 2180 (220g round nose) with 7 grain Vectan AO. I get allways about 1000fts. perfect group untill 80yards. I thought you had them too. Happy your back, i got tiered from Scotty Kilmer
It’s not failure to find negative results. You have saved someone else the time, money and energy of testing that bullet combination.
After watching you for a year or two, I'd say that it's time to build a shooting shack, gazebo, ramada... what ever you want to call it. Will keep you out of the sun, rain, snow etc.
thank you for the video .I am going to build me an Ar style rifle and now I am sure if I decide on the 300 BO it will have a 16 inch barrel .thanks for the info
I laughed my ass off at the clip from Master Ken. 6 years later and I can't watch that video without laughing.
Rainy day in Pennsylvania, and now something to ease the boredom
Hey Johnny, love your videos and all the data that you create in them. If I could make a suggestion without knowing anything about your audio/video processing software, I would recommend putting on a mild compressor and high frequency limiter for the viewers pleasure. It prevents the gunshots from being way louder than the rest of the video by using a compressor and the frequency limiter (high pass filter) prevents certain noises from having a sharp hiss to them. It's super easy to set up and I'd be more than happy to talk more about it with you.
Hey Johnny,
Hope the plum softening exercise is complete.
Looking forward to seeing a notification of a new video from ya.
I’ve been reduced to watching LabRadar promotional videos!
53k subscribers. Might be time to add a zero to the plaque on the wall 👍.
He should at least upgrade to a metal one
Plywood seems fitting given how UA-cam treats any channel in the genre.
You are a diligent bean counter like us sir good hard work
Love the 300 blk videos. Keep em coming!
Awooga! Welcome back J Man. ✊
Thanks for the video - it was really educational, and in a demented way kind of fun....
Thanks for another good video! Despite the NBT failing, it was informative and enjoyable.
Have you considered trying 277 Wolverine?
Also, have you considered trying some Shooters World powders (Blackout or Socom-SBR)? They're supposedly really good for both the 300BLK and 277WLV, but I haven't had opportunity to try it in either caliber yet.
Thanks again
Excellent video, I learned a lot with this one.
Sorry for your struggle. But it was all interesting. Thank you
Another enjoyable vid. from JRB! Thanks!
This video was definitely informative and entertaining
Nosler should recall these and save their reputation. Sorry Nosler, but I'm just a consumer that won't be buying these. Thank You Johnny!
Start off by saying I love your videos. I'm a subscriber. I've been following this 300 thread all the way through as I am considering a blk build. But with all the troubles you've had with heavy subs, it's got me wondering if it's even worth the hassle.

Or is this round just not worth the trouble?
He’s back!
I just bought two different powders.... That are recommended for Budget. So I'm gonna work on a SUB with TITEGROUP and a SUPER with Lilgun
Flavors are 130 gr, 150fmj, 168gr partition, 150gr SP.
Small rifle & small rifle MAG snappers.
Round performance was disappointing, but hopefully they get better with possibly more testing. Probably know more then me but i would put a couple more rounds of regular supersonic rounds through that barrel as well, it being so new. I like to break in brand new barrels, and i tend to get better performance out of them when i get at minimum a couple 100 rounds through them.
Well done, I’m struggling with my loads too. Maybe there’s no help. The SMKs at the end shot well.
It's been a year and 4 months, still time to get one in before that year and a half mark.
johnny, I have had no stability issues with this bullet. I am running a 10.3" daniel defense barrel with aa1680 and a c.o.a.l. of 2.100". I think your poor expansion was due to the bullets impacting the gel at an angle(you can see the angle on the ends of your bullets). I shot mine into milk jugs full of water and they acted like varmint bullets-complete fragmentation. They didn't mushroom and stay together at all, there were just tiny bits of lead and jacket pieces throughout the jugs. I would definitely explore it further. since you can shoot on your own property, I suggest maybe just prepping your brass, load 2 or 3 rounds and test stability, then go make adjustments-load two or three more, and test again vs. loading a large batch and finding out it's unstable-this is how i develop subsonic loads to save components. by the way, so glad to see you getting the blackout back in the mix, was getting really bored with all of the 6.5 and 308 videos hopefully you'll get back into the blackout
At what velocity was this fragmentation?
@@amagfoley 1000fps +/-30
Thanks for the video! Maybe a longer barrel would help to stabilize those guys?
Accuracy is good with 220 grain Subsonic Ballistic Tip" T/C Encore (1in 7 twist)barrel , under a inch with perfectly round bullet holes at 100 yards. Expansion sucked ,but did use one to kill a whitetail buck, velocity 1050ish FPS, 40 yard shot, next to no expansion, bullet tumbled exit was the exact length as the bullet is long.
Lube has dimension. 0.002 is preferred in engines. If a one thousandth thick layer can support thousands of pounds of force, then it can probably affect your sizing.
I'd really like to see a video on 245gr cast lead 300blk with cfe blk out of your 10.5 in barrel
I have one of the cheap 16" AR Stoner barrels. Shoots great, and for the price its got to be some sort of voodoo.
Jb bore paste the inside edge of seating stem does wonders
you won me over with that pistol and scope
I would really like to see what you could do with titegroup in 300 blackout
