AAC 5.56 Ammo Evaluation

So the AAC 5.56 is US made brass case 5.56x45 NATO with 55gr. FMJ. I bought some to test out because $.40/rd for US brass case is pretty good in today’s market, especially when sold in 20rd boxes.

I got real curious and decided to really dive into the ammo with disassembly and component inspection, velocity data and an accuracy/precision evaluation. PDF attached with the write-up and photos. Feel free to share, just please don’t repost without crediting or attributing.

TLDR - decent US made 5.56 ball for a good price

AAC is branding ammo huh? What’s the headstamp?

So that’s the funny thing. Both AAC (Advanced Armament Company) the suppressor company and AAC (America’s Ammunition Company) the ammo company are owned by the same holdings company that owns PSA among others. I break it down a bit in the PDF.

The headstamp is “AAC 5.56 NATO”, pics in PDF.

Interesting. I wonder how the availability will be.

Another USA Ammo manufacturer is definitely a good thing.
Hopefully at some point they’ll sell primers….

Appreciate your effort.

Thanks for the writeup.

Ever look at ammo and wonder if the brass is as bad as the ammo? Even my hastily reloaded garbage and Tula have consistent projectiles.

You’re quite welcome, it was a fun little project. I’ll probably do one again but make improvements on the process from what I learned this first time around.

Though not pretty, the brass does look good. I’ll process it the next time I’m ready to run a load through the tumbler and see what we get. Even with two different projectiles, I’m OK with how they shot. I’ll buy more, even if just for range fodder.

I’ve been keeping an eye on it. It comes and goes. I’ve not seen it unavailable for more than a day or two. I think Atlantic just recently sent an email blast out about a big shipment they received.

If it shows up locally, I might grab a box to play with. But anymore… we never shoot 55 gr FMJ. Heavier stuff is easier on the steel targets.

That velocity is better than what Buffman had recorded it but it could be a difference in lots and/or environmental conditions at time of the test.

Thanks for the info.

Somebody correct me if I’m wrong, but that brass looks like it was simply not tumbled again after annealing.

Most factory ammo is tumbled after annealing to make it pretty and shiny, but for example FGMM in 7.62 (as compared to .308) is not, and the annealing remains visible.

AFAIK, it’s a purely cosmetic thing…

I didn’t click the link, but yeah… that would make sense.

Pappabear and another buddy just bought AAC 77 gr OTM ammo at about $0.55 per round from Palmetto State Armory. Apparently out of stock now, but we’ll get to shoot some of this next weekend I’d guess.

(edit: Man… they show TMKs, SMKs, and even the TSX bullets that the gays love as ammo options… Everything is out of stock now, but it’s interesting the options you can get)

You are incorrigible mark. Love it!
Just color me “gay” then. (-:

:lol: If PB got a TSX wild hair, I’d go on reloading strike.

I bought 500 rounds so I am really hoping it shoots well. There was a point in time that Outback ammo had 69 SMK’s for .33 a round and I bought a case, but wished I had bought 10 cases. Because that is what an SMK cost at the time. So, when I saw this, I was thinking I better at least grab a few.

Range report to follow. Smart way for them to get the word out on their ammo. Sell an initial lot for cheap, for about the cost of a bullet and primer for gods sake. Be interesting to see if they continue this pricing, which I doubt.

Did you guys order the AAc / PSA 77gr made bullet ? … or the 77gr SMK AAC version ?

I’m sure they went SMK… I didn’t see another 77 besides the TMK. Either way, we’ll put some pics and stuff up next weekend.

SMK 77gr … “The 5.56 77GR Sierra MatchKing® HPBT Ammunition from AAC”… no cannalure.

AAC 77gr bullet… “Bullet Type: AAC Open Tip Match (OTM)” The $10.99 / 20rds stuff… and has a visible cannalure

I don’t know yet… but the AAC 77gr hollow point might be larger then the SMK hollow point. Sure looks like it in some pics I have seen.

Look again at the closeups. Both have visible cannelure…At least in the pictures provided by PSA. In fact they both look identical.
