PSA/AAC is doing great things. Outside of Magtech it was always hard for me to find a consistent performing 77gr load (none of my guns ever liked IMI). It’ll be nice to have a load that I think (hopefully) will be in stock/able to stack deep. While I would like to see a bit more velocity on the AAC offering, for the price and accuracy I can’t complain. It seems to run about 60-80 fps slower out of my main 2 precision AR’s compared to CBC/Magtech, but still plenty good to 600-700 yards. Sealed bullet and primer would be nice down the road maybe too. Magtech has claimed their 77gr will be back in production this year since they had pricing issues with Sierra and started producing their own projectiles too. We will see how they fair with all that. Of course there will be some issues to work out with a new facility, machines, etc. it’ll get worked out, good to see direct communication from PSA in these threads. Excited to try the .308 and 6.5 stuff when it comes out! |

Are the headstamps the same on both the AAC 77gr loads, IE the SMK load and the "Precision" load ? |

I started in the upper left getting the optic zero’d and then fired groups, adjusting 0.3mil right between the first group and the remaining 2. The G upper was quite surprising. I shot the middle group, then the two on the ends. I adjusted my hold technique after the middle group and each subsequent group had 4 very close together. It impressed me; as I don’t use a LPVO often. I think that running a different magazine or tweaking the gas tube could help the upper, but the ammo shot very respectable imo. https://i.imgur.com/ykJmBU8.jpg https://i.imgur.com/v8xDD8t.jpg https://i.imgur.com/svob2AW.jpg View Quote Yeah those Geissele groups are a little rough.

Going to grab 200 rounds and I'll post chrono results when I get it. I did like the 75grain so we will see how this does. And I'll let you know if I see any mangled ones.

Shot my ammo today out to 600 yds. Couldn’t get velocities as my buddy with the MagnetoSpeed couldn’t make it to the range due to work. It was holding .8-.9 MOA all day out of the White Oak 16” SPR barrel with the AEM5.
None of the boxes I’ve opened so far have any dents or defects. For the money the ammo can’t be beat. I’m happy. I will also mention I put in 2700fps in my ballistics calculator. That had me at 4.8 mils at 600yds. I was shooting high and needed only 4.6 mils to make x-ring impacts. |

It will be interesting to see the results of any ballistic gel testing with this load.

Has anyone else had any more use with it?
I’ve heard some people have been making returns back to PSA. I should be able to try some of mine this Saturday. I believe my lot is exclusively #SCL1CC241 as well. I wouldn’t be thrilled if I’m getting 25% failures like others have mentioned. |

Good to know it’s been consistent for folks here so far.
I’ll run some thru my Sionics upper this weekend. I’ll also have a buddy who owns a DD run some through his. I hope to post some 5 round group sizes of this compared to some IMI 77gr razorcore vs standard 55gr. PMC. |

I finally made it to the range twice today because someone didn't bring all the ammo or check the chronograph battery.
![]() I used my 18" rifle that I use for local gas gun and occasional PRS matches. Trigger is a Geissele HSNM adjusted to near the recommended minimums, and it's topped with a Nightforce ATACR 4-16x42 FFP scope with the mil xt reticle. Barrel is an 18" Larue Stealth with M4 ramps that has around 2 - 2.5k on it if I had to guess. Groups were fired from a bench, using the bipod up front and a gamechanger/fortune cookie style bag under the stock. It was sunny, low 80's with some gusty winds here and there. Typical PA springtime... It's historically liked IMI Razorcore 77gr ammo, and is good for 7/8" to 1" groups in my hands. I'd like to believe I'm better than that, but I don't have any precision bolt guns to see if I actually am, so I'll have to consider that the baseline. ![]() My test process wasn't the most scientific, but I tried to keep a fairly level playing field by firing 5 rounds, switching targets, chronograph strings and ammo, then firing 5 more and working my way through the selections. Then I worked my way back through the collection for a total of 10 rounds of each ammo on each target. Then I switched target colors, since I seemed to be shooting better at red aiming points and repeated the process, although I ran out of Black Hills. Finally, to wrap things up for giggles I fired 10 rounds each of IMI and AAC about as quickly as I could get settled back onto target, since my eyes were starting to struggle a bit. Chrono data is in reverse order: Black Hills 77 grain. I don't know which box color this was, as I traded with a friend for the loose ammo a couple years ago, and just had a couple rounds remaining. The 9 shots my chronograph picked up were 2650, 2624, 2645, 2624, 2629, 2583, 2619, 2614 for 2623 fps average, 67 es, 20 sd. ![]() Or dropping the worst shot or two, in case I was responsible for a flyer or two: ![]() Frontier 75gr Hornady : I picked this ammo up last season because some of the guys I know were having pretty good luck with it and it was a good bit cheaper.

I'll counter with my shooting and IMI ammo today: 1.46", 2.08" and 1.03" for an average of 1.52". I know IMI can shoot in this rifle, so I believe further head to head testing is in order. It’s been at least 12-18 months since I've shot for groups, and there's some variability that I need to chase down. I'll give you that the extreme spread and standard deviation are higher than almost everything I shot today, which means there's room to improve the product. I see potential there, and given the progress they've made in the past decade or so, I'm not counting them out. I'm going to test it at distance during one of the upcoming gas gun matches, and as long as it behaves at around the level that my 100 yard testing indicates, well...it'll be my new favorite, since 150-200 rounds of 75/77gr plus match fees add up quickly these days. ![]() |

It’s been at least 12-18 months since I've shot for groups, and there's some variability that I need to chase down. I'll give you that the extreme spread and standard deviation are higher than almost everything I shot today, which means there's room to improve the product. I see potential there, and given the progress they've made in the past decade or so, I'm not counting them out. I'm going to test it at distance during one of the upcoming gas gun matches, and as long as it behaves at around the level that my 100 yard testing indicates, well...it'll be my new favorite, since 150-200 rounds of 75/77gr plus match fees add up quickly these days. ![]() View Quote Thanks for sharing your results.

I've seen nothing but a desire to provide quality products, and a willingness to iteratively improve. Until then, I'm staying in the corner with some popcorn as the adults in the room produce valid data and insight. |

Trigger is a Geissele HSNM adjusted to near the recommended minimums, and it's topped with a Nightforce ATACR 4-16x42 FFP scope with the mil xt reticle. Barrel is an 18" Larue Stealth with M4 ramps that has around 2 - 2.5k on it if I had to guess. Groups were fired from a bench, using the bipod up front and a gamechanger/fortune cookie style bag under the stock. It was sunny, low 80's with some gusty winds here and there. Typical PA springtime... It's historically liked IMI Razorcore 77gr ammo, and is good for 7/8" to 1" groups in my hands. I'd like to believe I'm better than that, but I don't have any precision bolt guns to see if I actually am, so I'll have to consider that the baseline. https://www.ar15.com/media/mediaFiles/316444/20230412_194455_jpg-2780265.JPG My test process wasn't the most scientific, but I tried to keep a fairly level playing field by firing 5 rounds, switching targets, chronograph strings and ammo, then firing 5 more and working my way through the selections. Then I worked my way back through the collection for a total of 10 rounds of each ammo on each target. Then I switched target colors, since I seemed to be shooting better at red aiming points and repeated the process, although I ran out of Black Hills. Finally, to wrap things up for giggles I fired 10 rounds each of IMI and AAC about as quickly as I could get settled back onto target, since my eyes were starting to struggle a bit. Chrono data is in reverse order: Black Hills 77 grain. I don't know which box color this was, as I traded with a friend for the loose ammo a couple years ago, and just had a couple rounds remaining. The 9 shots my chronograph picked up were 2650, 2624, 2645, 2624, 2629, 2583, 2619, 2614 for 2623 fps average, 67 es, 20 sd. https://www.ar15.com/media/mediaFiles/316444/20230412_194723_jpg-2780296.JPG Or dropping the worst shot or two, in case I was responsible for a flyer or two: https://www.ar15.com/media/mediaFiles/316444/20230412_194735_jpg-2780298.JPG Frontier 75gr Hornady : I picked this ammo up last season because some of the guys I know were having pretty good luck with it and it was a good bit cheaper. I didn't have time to shoot for groups or chrono data before the a couple of matches, and while it shot OK, I could tell it wasn't as consistent as the IMI I usually use. 15 shots registered on the chronograph: 2721, 2743, 2766, 2749, 2766, 2743, 2704, 2749, 2732, 2645, 2682, 2677, 2688, 2661, 2672 for 2713 average, 121 es, and 40 sd. https://www.ar15.com/media/mediaFiles/316444/20230412_194653_jpg-2780305.JPG https://www.ar15.com/media/mediaFiles/316444/20230412_194707_jpg-2780310.JPG Or dropping 1-2 shots as above: https://www.ar15.com/media/mediaFiles/316444/20230412_194848_jpg-2780308.JPG https://www.ar15.com/media/mediaFiles/316444/20230412_194913_jpg-2780311.JPG IMI 77gr SMK: My chronograph picked up 16 rounds during the standard string of fire at 2624, 2682, 2614, 2619, 2666, 2661, 2614, 2614, 2604, 2629, 2614, 2578, 2661, 2635, 2614, 2588 for 2626 average, 104 es, 28 sd. This was about 50 fps slower than my historic recorded speeds - it might be about time to clean this rifle again.

Ejection was around 4:30 with no noticeable distinction from the other rounds fired. I'm not a brass or primer expert and didn't spend too much time going over the pieces in detail. But there were a handful of pieces from each manufacturer that had some small dents in the body and scratches around the neck, but I didnt spot any trends. Some brass, particularly the Black Hills (and the IMI to a lesser extent) exhibited light ejector swipes/marks. The AAC primers looked very similar to the Black Hills in terms of dimple depth, while the IMI was appeared deeper and wider.

I really like this ammo. I was ready to buy a bunch of the 75s when I got home from the range but it was all sold out
I tested this in our 16" DD .625 lightweight barreled factory upper with a Leupold Mk6 1-6x 5.56 CMR-W. I compared AAC 75gr, AAC 77gr SMK, IMI 77gr Razorcore, and our 75gr Hornady BTHP handloads that I had worked up for a previous service rifle barrel that shot well in subsequent WOA service rifle barrels and a few of our mil-spec barrel builds too. I shot 1 5-shot group each at 100y and got velocity data. This is how it fared: 69.4F, 27.54 inHg, 19.5% humidity Hornady 75gr Handloads: 1.25", Avg velo: 2707 fps, 20.8 SD AAC 75gr BTHP: 1.15", Avg velo: 2721 fps, 14.2 SD AAC 77gr SMK: 1.5", Avg velo: 2699, 16.7 SD IMI 77gr Razorcore: 1.2", Avg velo: 2671 fps, 31.7 SD The AAC 75gr shot the best, had good velocity, and had the best SD. Hilariously it also also zeroed better than our Hornady 75gr handloads. Since the Mk6 has .2 mil clicks, you can be slightly high or slightly low between clicks, it just so happens that our zero is slightly high. However the AAC 75gr had better elevation. Here's a pic of the 50y POI shift, as I wanted to see the shift in order to dial it out on the turrets. They're just 3-shot groups at 50y: ![]() ![]() Then I shot some mid/LR on steel with it. Here's the first run with the ammo. It seemed to do well and the price is really good. I'll definitely be buying more of it |

I bought 200 rounds to break in my new White Oak 18” SPR Barreled upper.
I’ll be buying more. Since i’m not real good at shooting groups I’ll share my chronograph data. I’m was surprised at the velocities. I did check the case head expansion for signs of over pressure and they all looked normal . I did have a Griffin Armament Recce 5 mounted , not sure if that would’ve made a huge difference. Lot # SCL2CC301 Max.. 2899 Min.. 2847 ES..52 AVG..2863 SD..14.4 1. 2859 2. 2856 3. 2862 4. 2856 5. 2853 6. 2863 7. 2858 8. 2848 9. 2874 10. 2899 11. 2852 12. 2867 13. 2853 14. 2869 15. 2847 16. 2882 17. 2850 18. 2871 19. 2858 20.2894 |

Holy crap that’s moving! Even the AAC 75gr I shot through my WOA 18” barrel wasn’t that fast. It averaged 2760 fps. Seems the AAC 77gr bullet flavor is quite a bit faster than the AAC Sierra 77gr.
