I ordered this ammo 6-17-25 Stated 2700fs on the box and received 2550fs on box called them and they would not help. Will not order from PSA in the future

Don’t put unleaded in your Ferrari, I guess.
From a Criterion CORE 18” . 223 Wylde barrel with a 4-16 Nightforce ATACR and bagged and bipoded, this ammo is grouping 2. 25” at 100M. Only positive is it had a 12. 1 SD, but I’ll be waiting to see if I can get the 2700FPS stuff again. Buyer beware. Not a precision round.

Review by Paul l. on 6 May 2025review stating Buyer beware
Unfortunately, this ammo has pad, many reports of catastrophic failures and even destruction of firearms. I stack three thousand deep, but I haven't shot any and I don't want to risk an expensive firearm with ammo. That might not have good pressure. I contacted psa to find out about at least bad case locks, so I could avoid a catastrophic failure. They wouldn't even give me that, so now I'm stuck with 3000 rounds of ammo that I won't shoot because I don't want to risk a gun being destroyed and the feud of Heather guns destroyed only got ammo refunds, but they had to eat the cost to replace the damaged rifle. I contacted p S. A. they refuse to give me any information instead. Just give me some blanket statement about how great their ammo is. real nice customer service Just watch 110 sass actual video on you tube. Its a shame
Review by Brandon J. on 25 Apr 2025review stating I ran a head-to-head comparison
I ran a head-to-head comparison of AAC 77gr OTM against Barnes and Nosler 77gr match ammo out of the same rifle on the same day, under the same conditions. Both the Barnes and Nosler ammo consistently produced sub-half MOA groups, proving their reliability and precision.
Unfortunately, AAC’s performance was extremely underwhelming. The best group I could get was just over 2 MOA, and average groups were in the 3 to 4 MOA range—completely unacceptable for a load marketed as match-grade. No amount of careful shooting could overcome the inconsistency. Same rifle, same setup, same conditions—only the AAC failed to deliver.
This isn’t match ammo—it’s barely acceptable for general use. Spend the extra and go with Barnes or Nosler.
Review by Emilio S. on 23 Apr 2025review stating I've never seen something like
I've never seen something like this before. Flash hole was present. It spewed smoke from the breech and charging handle. Another one the same box necked itself entirely into the case on first chambering. Luckily I cleared and didn't fire from that mag. Sent pics to support but not response. Sucks because I've stacked this stuff deep and I'm a bit sketched out on it.

Review by Timothy R. on 23 Apr 2025review stating Ammo now much slower
I have had great experiences with this ammo in the past. Unfortunately the new batches are much slower. The old batches gave me 2600fps with . 75 moa groups and the new batches are going 2450fps with group sizes ranging from 2. 25 to 3 moa.
Review by Lee D. on 17 Apr 2025review stating Shoot better than me out
Shoot better than me out of my Rosco K9 11. 5. Usually have 1 flyer out of a group no matter 5 round or 10 round but for the price and my capabilities, I am pleased. Will and have bought plenty more. I just hope they stay the same per round or better yet, go down!
Review by Ryan on 13 Apr 2025review stating Very Accurate and amazing price!
Overall this is good ammo for a good value.
This review is based off of shooting a Colt M4A1 with a 14. 5in SOCOM Barrel with a Trijicon TA 31 ECOS Optic
Pros. This ammo grouped very well. Shot it in a know distance range out to 500 meters and the groups at all ranges when I was calling wind appropriately were very good.
Pushed it to 800m on a steel target and got 7/9 hits with that 14. 5in barrel.
Cons: I am ocd and clean my rifle after everytime I shoot and noticed this ammo is significantly dirtier than what I have been shooting.
Compared to other ammo where my ejection pattern is at the 3-4 O’Clock. This ammo was consistently ejecting at 1 O’Clock with a standard carbine buffer spring and a H2 buffer.
I tossed in a Sprinco Hotwhite (intermediate power spring) and a H3 Buffer and that seemed to tame it down a bit. I am thinking I will likely have to use springco’s blue spring if I run a suppressor on this rifle.
Review by Scott C. on 10 Apr 2025review stating Hard to beat this ammo!
Hard to beat this ammo! I am nearing 1k rounds. 500 down range all ready. This is a site in target at 100 yards from an AR15 with a 16" 223 wylde barrel. Really can't say enough about how well this ammo groups. I am hitting steel out to 400 yards, every range trip.
Great preformance but SDs are potentially an issue
Review by Nocturnal B. on 2 Apr 2025review stating Great preformance but SDs are potentially an issue
The rounds generally do great. I've only had a few flyer (on average maybe one in a hundred). Here's some data that managed to capture the deviation of a flyer. Otherwise, outstanding ammunition.
Review by Blake B. on 27 Mar 2025review stating It’s true. They dropped the
It’s true. They dropped the powder charge in these and they’re a complete waste of money now. Averaged 2510fps out of 16” Criterion on 10 round string. Lost all faith in this brand, won’t be buying again. It’s complete false advertising and terrible ethics for a company who claims to be all for the customer.
Review by Dan B. on 13 Mar 2025review stating SLOW AF
Cameron with PSA has confirmed to me through email that they changed the powder on this load and it slowed it down >250fps. He claimed they don’t have time to change the website to reflect the real velocity numbers! I was only getting an average of 2470fps out of a 18” white oak barrel. The same barrel shot IMI 77gr at 2801fps average… so it not the barrel, it’s the crappy ammo they are selling with false advertising! Notice it’s always on sale?… they are trying to dump their crap ammo on its customer! Bad business ethics! Are they Democrats???
Review by Simon on 10 Mar 2025review stating Inconsistent lots of ammo
I ordered this in bulk and was getting 2659 fps average velocity, was very happy. My last lot was getting 2463 fps. Got in contact and psa said they switched their powders, but failed to advertise this. Now I'm stuck with slow ammo. I hope this doesn't happen to anyone else. Won't be using this as cheap match ammo going forward.

Review by Neil H. on 10 Mar 2025review stating Not so great
First batch I had was shooting around 2650 fps out a 16” wylde. This last lot is not even hitting 2500, and a lot of others are saying the same. It was awesome when it was…
Review by Ely S. on 9 Mar 2025review stating Shot fine, Chrono’d horribly
Functioned flawlessly. No dented cases or unusual coloring as seen in other reviews. When chrono’d, the muzzle velocity was lackluster. They advertise 2700 FPS on the box. Out of 2 different 16” barrels (one is a SOLWG and the other is a POF) the muzzle velocity average didn’t even get up to 2400 FPS. I tested it out of a 12. 5” BA barrel and averaged >2300 FPS. The standard deviation was less than ideal as well, ~30. Lot number is SCL2EA302. Included in my photos will be a chrono for 62 gr. PMC XTAC out of a 16” barrel for comparison. In short, this is now plinking ammo only.

Review by Spencer B. on 4 Mar 2025review stating Decent ammo for the price.
I love it for the price. It doesn’t shoot as consistent as I would like it. Can’t find this heavy and type of bullet for the price or near the price anywhere else. Shoots great out of my 20”ss. 1/7. At 100yds
Review by Christian K. on 4 Mar 2025review stating It was accurate and functioned
It was accurate and functioned well but the velocity was much slower than expected. Under 2450 in a 16” barrel with the SD in the mid to upper 20s. Still very good for the price.

Review by Andrew W. on 24 Oct 2024review stating Excellence performance at an exceptional price
This stuff is phenomenal, not just for the price, but period. Palmetto State and AAC are the unsung heroes of the Everyman gun owner. @ 50yd, through my 11. 5” Sig Spear LT, with an unmagnified Aimpoint T2, the illumination dialed down as low as possible yet the dot still bigger than the bullseye, it STILL puts multiple impacts nearly touching in the bullseye. In the picture, you can see I took 2 shots at a random piece of cardboard, at what I perceived to be the center, and the holes are touching. Granted this is out of a high quality weapon, with a high quality trigger (Geissele SSA-E), but the fact that ammo for 62 cents a round gets these results is, to me, absolutely stunning.

Review by Patrick M. on 11 Apr 2024review stating Top notch ammo
Very impressed with this ammo, I snagged a bulk amount on sale and recently had a chance to test some out. Every round went boom, no failures at all, and very accurate out of my 18" SPR build. I'll be keeping an eye out for sales in the future and stocking up.
Review by Beau N. on 13 Nov 2024review stating Shot great for me.
My LWRC DI with a 1/7 twist barrel really seems to like this stuff. Shot a couple groups at 50 yards just for a quick test. I was on a bipod with a rear bag so there could have been a flyer or 2 that were on me but i was happy with the results.

Look man, I stockpile it. Best bang for your buck.
Review by Patrick G. on 17 Nov 2024review stating Look man, I stockpile it. Best bang for your buck.
I did some testing on this ammunition and I was getting on average 1-1. 5 MOA for 5 round groups, and under 2 MOA reliably for 10 round groups out of a 16” BCM upper. This ammunition in my opinion outperforms other brands and it seems like they got some of the primer issues sorted from the past which is a plus. I used a chronograph and I got an average velocity of 2620. 7fps with a SD of 10. 2. Ammunition performs good under windy conditions and I got good effects at 500yds. I’ve yet to do further distances with it.

Review by Anonymous S. on 25 Nov 2024review stating Its as good if not better than the Sierra 77gr.
This ammo is a bit more accurate than the AAC 77 Sierras that Palmetto sells and is hard to get some times. The current sale price for this is $10. 99 a box . . wow. I also buy the Sierra 77gr projectiles and make my own version of the MK262 that shoot sub moa 5 shot groups. With this ammunition Ive shot several 5 shot groups from a MK12-0 clone(1/7) and NONE were greater than 3/4" at 100 yards. on a bench with a bi-pod, low wind. I also shoot this ammunition from a Daniel Defense MK18 RISII 10. 3" barrel 1/7 with an EOTECH and get sub 2" at 100 yards. with a sand bag on a bench low wind.
