I'm convinced, after 45 years as a rifle shooter, that you could buy two sets of identical parts, build two rifles, and they would shoot differently. I took a long-range gas gun class last November, and started my load development in early September. The class syllabus said we needed 500 rounds of ammo, all from the same lot number, so I started buying commercial ammo, on the off chance that I'd be able to buy rather than handload. I bought Sierra, IMI, Federal GMM, Hornady Match, Hornady Black -- all together, I think I bought 16 different boxes, in the 68-77 grain weights, and in both the 223 and 5.56 pressure levels, and I couldn't find a single load that my rifle would shoot at the level I wanted. Nor would it shoot my 223 bolt gun pet load, which is the Hornady 68 grain OTM bullet on near max load of RL-15, which will shoot a 0.40" group out of my Savage 112 any day. I finally found that the BA barrel with a 1:7 twist liked the Hornady 75 grain OTM, and developed a load of about 2790 fps that would shoot under an inch at 100 yards. Then I proceeded to load 700 rounds for the class and the last day match. But I know that if I had a second, identical gun, it would want a different load. Rifles are ridiculously fickle. You've got a nice rifle there.
I'm a CNC machinist and I can tell you why they're all different. Every time you cut the rifling on a barrel or turn down the outer diameter with a lathe or ream it out or any machining operation the amount of WEAR on the tooling is different. The machine allows us to compensate for wear, usually we do that in very small increments on critical tolerances. I usually start at +0.0050" and work my way down to -0.001" to -0.0013"ish max, if I have to go that far I get new tooling. I go in increments of -0.0003" and check by hand or with the probe in my machine after each cycle. Now, I'm not machining barrels. I am machining tooling actually. So, its super critical for what I machine to be essentially perfect. I'm just explaining a common practice. So, depending on tool wear each barrel will be different. If its a brand new tool obviously that'll produce a different result than a tool that has already made 10 barrels. Then of course assembly plays a role too. That's why torque wrenches and drivers are so important. With AR15s I also bed my barrels using green loctite retaining compound. I learned that from Mike Ross who is the CEO of Criterion. There is debate online as to whether it's worth it to bed a barrel since it can be a pain in the ass if you need to take the gun apart later on. Recently I built a 12.5" using a Geissele barrel and a SOLGW stripped upper+m89 rail and in that case I DID NOT bed the barrel just to see if there is a difference. So far that 12.5" has been very accurate so I can't really say there is a huge advantage to bedding or not.
My BA barrel seems to be the same, never had a gun be so picky with ammo. 75gr Hornady black is sub 1in at 100yds, 62gr of 4 other manufacturers is like 2.5in. Same ammo out of another upper shoots 1.5 or less which is acceptable for a rds/magnifier. Was incredibly frustrating trying to find what it liked.
I fired 20 AAC 77gr Sierra OTM rds from my 20in FN M16A4 military series rifle, and averaged 2,810fps! I used a Garmin XERO chronograph. 91-93 degrees, high humidity, and around 500 feet in elevation. Standard deviation varied but averaged 26.1. From an 11.5 barrel, velocity of 10 rds. averaged 2460.3.
I've been using AAC ammo in my Primary Weapon Systems 5,56 AR-15 tactical rifle and my Armalite AR-10 Super SASS Rifle for years, and you cannot beat the price, quality or performance.
@@MikeSmith-pq4wz I agree. I've seen a few guys on here dumping on AAC. Could the SDs be better? Maybe a little, but for factory ammunition it's great. It's comparable if not better than most.
I just picked up 15 boxes of the OTM to try out in my 16” mid length “gpr”. Or whatever you want to call it. Basically my 400-500 yard MAX gun with a 1-8 lpvo. As long as the barrel likes them I am happy with the velocity and accuracy of those for the price.
Good comparison, I appreciate the data. I’m an IMI 77gr shooter. My SD’s are in the same ballpark as these loads, but velocities are almost 2800fps out of my 18” Douglas. AAC is tempting, but losing that much velocity is a dealbreaker for me.
Thanks for the video, I think the OTM's are good for extended long range, they don't wobble when going through the sound barrier. Otherwise, I've found them to be not as accurate as good target rounds like the SMK or Berger hybrids or other BTHP bullets. That's been my experience, anyways, thanks again.
I haven’t shot any of the aac 77gn stuff yet but I’ve shot a lot of the 75gn bthp and 75gn saber. And both of those avg just a touch over 2500fps from my 12.5” and 2580fps from my 14.5” usually shoot 1.5 moa sometimes better. For the price though that’s all I buy is the aac. I actually just ordered 500rds of the 77gn that was on sale for $9.99 a box over the holidays. Waiting on that to come in now. The 62gn saber from aac has done quite well for me also.
Interesting. I don't think I had as good results with the AAC as I do from Freedom Munitions 77gr 223 and 5.56, remanufactured or otherwise. Thank you for the video!
@@ReticentIndignation each ammunition is gonna act differently in each individual rifle, yours may like the Freedom better. Barrels are like that. Kinda how I like skinny blonde haired women. Don’t know why, I just do. Lol

The Hanson BA 18” SS barrels come with the gas block installed by the factory, which I feel will give you a tighter fit sealing any gas leakage, and the Hanson series gas block comes with a cross pin.

@@rudolphferdinand3634 no, the stainless barrels do not have installed gas blocks. Actually in my experience most gas blocks leak somewhat. Most will seal up within a few hundred rounds. Not ideal for sure.
PSA I’m sure is rating their ammo speeds out of an AR, while that Federal ammo is 223 and likely rated from a 24” bolt gun. When you started this test I expected the Federal numbers to be slower than advertised. Nice rig.
My Criterion 20" hybrid gets 2680 FPS out of that same FGMM 77 grainers (and this was measured at 32f weather.) Criterion barrels seem to be a solid 100-150 fps faster than other barrels. I think they slightly undersize the bore for this. Accuracy is about the same
@@RimfireSS I just received mine. Not sure if they’re heavy duty enough yet to protect your legs from burns under an aggressive firing schedule, but when I went to the range to confirm zero with my suppressor it mitigated the mirage effect well. I picked up the slick .030 thick one designed for 1.5” diameter suppressors. I’m hoping that further testing confirms its validity as a heat shield for my legs on my short boy. Really trying to avoid dropping 3 Benjamin’s and change on a liberty cover.
@@RimfireSS if the Manta doesn’t hold up to an aggressive firing schedule, that’s my next move and I’ll relegate Manta covers for heat mirage work. I’m retired and can’t afford Liberty for all my platforms and starting off with one as my first held little risk as it can live on my 16” with its ffp 4-14 scope. The Manta website recommends no more than a 100 round string before giving it a break. Most companies undersell that kinda number to give the product a little breathing room before failure. And the form factor was different enough to maybe be viable. I was a carpenter so how materials good up to heat exposure is beyond my skill set. The savings in cost and being confident it would be suitable for the 16 made the risk minimal. If it’s not up to it, high volume cans will get liberty’s. Not gonna bother with trying to find a work around at that point. The other quality covers of similar design to the liberty are expensive enough to not make the risk worth it.
223 Rem right on the box on the Federal. That has to be why it isn’t loaded as hot, annoying that their velocities are off but maybe they are using like a 24” barrel reference vs 18” since its 223 Rem vs 5.56NATO?
My AR 1:9 twist 😢 maybe time to get a 1:7 so I can run these heavier bullets! I’ve been running the aac 762 blade “hornady SST” amazing stuff Only thing that comes close imo is the PPU soft points
@@Grizzlyman420 I just ordered a case of the AAC 77 OTMs. They don't shoot quite as good as the Sierra Match King OTMs but hard to beat the cost. $11 a box for 77s. I'll settle for the performance difference.
@ I almost picked some up earlier online 😂 had em in my cart and everything. I’m sure even with my 1:9 twist 100 yards and in they’ll shoot just fine. I do have some of the 55 and 62 grain blade and they run great. 556 really shines though with heavier bullets. Those TSX Barnes” are nastyyyyy as well but I’m not spending 20$ on 20 rounds. I just got back on their site and they do have a 69 grain OTM so maybe I’ll try those when back in stock.
I didn't have good luck with the OTM out of my ballistic advantage barrel. I switched to criterion, and my groups tightened up, and my velocity was faster by about 100fps.

Hm I have a 16” BA government profile barel that shot 2650 fps average with 77otm . I bought the same 20inch barrel , but have not built it yet. I really hope I get more velocity with a 20 in , but scratching my head why your velocity is just a little higher than my 16” BA
@@colemangreen8938 there's probably only a 30-50 fps difference between a 20" and a 16" on a 77 grain bullet on average. Both barrels I am using are fairly new as well and will speed up as it breaks in. You'll be good, don't worry.
Federal way to slow! AAC Match King the winner. I run 77 Barnes Match Burner hand load at 2720. 5 fps SD in a 12.5" SBR. 18" doing 2900 no pressure. H335 with Fed 205ARM primer.
I've always had very good accuracy results with FGMM but that velocity difference is substantial. 200 BELOW advertised? That's crazy. Federal is scamming us.
@@armorers_wrench idk, some people were saying that Federal Tests out of a bolt gun and Aac out of an AR. That would make some difference but not 200 fps. For the price I’m definitely happy with AAC.
Sir that rifle will shoot better. Can I bet you a box of ammo that if you shed the suppressor you will turn in better groups with that rifle?😉😉 Thank you for sharing with us but I am very interested in this. I have shot with over 30 suppressors in different calibers and the groups were always smaller without. Now the question is does the shot group size being small by .3 to .5 make that much of a difference over the sound reduction and recoil reduction you get?
@@Dayattherange I bought the cam so I could shoot high power rifles at my home range without pissing off my neighbors. I will try it without the cam eventually.

That would be my reason to request the test without the can. That and cans can change the accuracy of ammunition.
@@jongruen7854considering how many people shoot PRS with a can (to include myself) the accuracy isn’t adversely impacted by cans. The PoI can change certainly, but that’s why you zero with a can. The only time cans can greatly impact a round is if the can is a heavy back pressure can and you’re shooting a round that your barrel twist isn’t rated for. Given that this is a flow 762, the can is far from backpressure laden, and the ammo is 77 grain which all modern ar15 barrels are absolutely rated for.

Not gonna bother with trying to find a work around at that point. The other quality covers of similar design to the liberty are expensive enough to not make the risk worth it.
@@christoperdevore3617 absolutely
223 Rem right on the box on the Federal. That has to be why it isn’t loaded as hot, annoying that their velocities are off but maybe they are using like a 24” barrel reference vs 18” since its 223 Rem vs 5.56NATO?
@@Ubergamer256 yup, that's why the velocity is so much less, 556 is always hotter.
Beautiful rifle !
@@marku123 thank you
My AR 1:9 twist 😢 maybe time to get a 1:7 so I can run these heavier bullets! I’ve been running the aac 762 blade “hornady SST” amazing stuff
Only thing that comes close imo is the PPU soft points
@@Grizzlyman420 I just ordered a case of the AAC 77 OTMs. They don't shoot quite as good as the Sierra Match King OTMs but hard to beat the cost. $11 a box for 77s. I'll settle for the performance difference.
@ I almost picked some up earlier online 😂 had em in my cart and everything. I’m sure even with my 1:9 twist 100 yards and in they’ll shoot just fine. I do have some of the 55 and 62 grain blade and they run great. 556 really shines though with heavier bullets. Those TSX Barnes” are nastyyyyy as well but I’m not spending 20$ on 20 rounds. I just got back on their site and they do have a 69 grain OTM so maybe I’ll try those when back in stock.
I didn't have good luck with the OTM out of my ballistic advantage barrel. I switched to criterion, and my groups tightened up, and my velocity was faster by about 100fps.
@@Bookof_rook Criterion is awesome, Mike is sending me a 18” core to replace this Ballistic Advantage with and we’ll do a comparison video. I have worked with Criterion on a couple other builds and there will be a lot more content coming.
When did they stop putting primers in 5.56? 😉
Gorgeous rifle, btw.
@@upStomp lol, thanks
I shoot the 77 grain FGMM and get about a half MOA from it from my match conditioned Service Rifle used in CMP governed Service Rifle Competition.
criterion barrels are what 2-3x the cost of BA/ AERO? they might shoot better but not 2-3x better!
This may sound crazy: I have a BCA barrel that shoots phenomenal! Problem is, I haven't been able to find a way for it to work consistently. FTF, randomly. 18" barrel, rifle length gas...
@@Abbynorml1979 could be a low gas problem, maybe the gas hole is too small.
I noticed the can being damp in some of those shots
@@moebrewer136 yeah, I had to pour some water on it, I mentioned it in the video. Was tired of waiting for it too cool off. The mirage was horrible.
Hm I have a 16” BA government profile barel that shot 2650 fps average with 77otm . I bought the same 20inch barrel , but have not built it yet. I really hope I get more velocity with a 20 in , but scratching my head why your velocity is just a little higher than my 16” BA
@@colemangreen8938 there's probably only a 30-50 fps difference between a 20" and a 16" on a 77 grain bullet on average. Both barrels I am using are fairly new as well and will speed up as it breaks in. You'll be good, don't worry.
@@RimfireSS thank you sir! I know I will also get a big jump improvement with 55gr too. I building my 20” for competition.
Good vid
Federal way to slow! AAC Match King the winner. I run 77 Barnes Match Burner hand load at 2720. 5 fps SD in a 12.5" SBR. 18" doing 2900 no pressure. H335 with Fed 205ARM primer.
I've always had very good accuracy results with FGMM but that velocity difference is substantial. 200 BELOW advertised? That's crazy. Federal is scamming us.
@@armorers_wrench idk, some people were saying that Federal Tests out of a bolt gun and Aac out of an AR. That would make some difference but not 200 fps. For the price I’m definitely happy with AAC.
@@RimfireSSI believe that generally .223 is tested out of a 24” barrel and 5.56 from a 20” barrel
@@Stryker309 that make sense
🇦🇺😎👍
There is literally no utility to a three shot group. None :-)
I agree. Wish I would have realized this a long time ago.
Sir that rifle will shoot better. Can I bet you a box of ammo that if you shed the suppressor you will turn in better groups with that rifle?😉😉 Thank you for sharing with us but I am very interested in this. I have shot with over 30 suppressors in different calibers and the groups were always smaller without. Now the question is does the shot group size being small by .3 to .5 make that much of a difference over the sound reduction and recoil reduction you get?
@@Dayattherange I bought the cam so I could shoot high power rifles at my home range without pissing off my neighbors. I will try it without the cam eventually. Shot a .23 5 shot group with a different rifle I have with a white oak heavy Varmint barrel with this same AAC match king ammunition, with the suppressor on.
@@RimfireSS I expect that with White Oak brother. I totally understand about the can I would have done the same thing.
Wow. For so called match ammo those SDs suck.
@@patdennis3751 I’ve seen much more expensive ammunition with worse SDs believe it or not. Actually on XRings latest video.
That Federal didn’t look sub MOA between those two shots spread out the furthest.
@@michaelthrelkeld212 that’s a 1” paster I was shooting at. Lol, I measured it with Ballistic X what else do you want? My Lord!
@@RimfireSS don’t get mad. I was saying it didn’t look that way.
@@michaelthrelkeld212 not mad, just stating fact. Lol but it does get old when people say that. That’s why I started using BallisticX. As long as you have a good basis measurement it’s hard to get wrong. But, not mad
Run the same test without the can.
Why a without the can? Most folks shoot every thing suppressed now days! All my guns are zeroed with a can.
@bulletjones119 Really? Most people. Or those on UA-cam or the real world? Some of us live in states that have banned ownership of cans. Other people do not budget $600 to $800 with the tax stamp. That would be my reason to request the test without the can. That and cans can change the accuracy of ammunition.
@@jongruen7854considering how many people shoot PRS with a can (to include myself) the accuracy isn’t adversely impacted by cans. The PoI can change certainly, but that’s why you zero with a can.
The only time cans can greatly impact a round is if the can is a heavy back pressure can and you’re shooting a round that your barrel twist isn’t rated for. Given that this is a flow 762, the can is far from backpressure laden, and the ammo is 77 grain which all modern ar15 barrels are absolutely rated for.
