View Quote View All Quotes View All Quotes Originally Posted By Jkees: Originally Posted By Jman_JJE: I have no information other than looking at the post quickly. My cursory take is that 77gr OTM out of a short barrel results in higher pressures and violent cycling. I believe this is why he is saying that the gun works with 55gr PMC/Winchester. The recoil pulse is different with 55gr. This can vary by weapon and depend on gas port size. To combat this Giesselle recommends that you use and H2 or H3 buffer in a 10.5 inch barrel. I’m guessing the combination of heavy buffer with the 10.5 barrel and 77gr projectile would make it cycle correctly. There is people commenting about this in the post, but since it is Reddit it is being ignored. Without getting his upper in and changing out his buffer I can’t prove it out but we would be willing to do so. We are working on a video showing proper buffer setups with short barrels and heavy projectiles. As a data point I have a 10.3" geissele super duty sporting a super 42 with H3 and with y'all's 77gr OTM I have not had any issues with any feeding. ETA: unsupressed. Do you know what gas port size you have? I’m assuming yours is the 0.075 port (crane spec is 0.070) since it’s functioning unsuppressed with an h3. iIRC there was G 10.3 barrels that had really small ports at around 0.063 that I would think wouldn’t function unsuppressed with an h3. |

They just added the Hornady name in the description.
However, it is not on the box like Sierra/Barnes, which I still don't understand. Likely just the nature of their deal with Hornady. 75gr BTHP is blue box, 77OTM black box. Both Hornady Match projectiles. Some changes to the box labeling would be good imo. Not catastrophic, but I have had a ruptured case with the 77OTM, bought in November 2023. (Posted in this thread). Their brass has had some issues. I shot the 120rds I had left from that lot with no issues since they didn't answer my email. |

So far I have seen a lot more issues with the 77gr OTM than the SMK loading which I find odd. Not to say stuff couldn’t happen with the SMK cause it could but that’s how all ammo is I suppose.

I did ask if people ran this stuff on the clone rifle page on Facebook and so far I’ve read a lot of people run it in their Mk12 builds so that’s very promising since the cloning hobby is very expensive, so I know those guys wouldn’t put shit ammo into their expensive clones. |

How do those perform in gel compared to Barnes? |
|

CX and GMX are Hornadys solid copper offerings, but they have polymer tips and none are 70gr .224.
I'm sure PSA will say they were made exclusivly for AAC and until someone does a side by side and some gel test we simply won't know. Jamin said they are conducting gel tests for everything to add to the website |

I'm guessing those would be aac answer to the barns tsx. The barns have been pretty hard to get and seems like a shortage of the bullet. I would l9ve to see how the aac 70gr sbx compares to the aac 70 tsx.

I shot my first 140 rounds or so of the OTM yesterday.
I started with a Remington 700 SPS Tactical. 18", 1/9 twist barrel, Nikon Monarch 5-20x44. It shot okay, but I'm used to shooting my own reloads that I've tuned just for that rifle so I'm not sure how the OTM stacks up against other factory ammo through this particular gun. I didn't write all the numbers down but there wasn't a huge FPS spread and it averaged 2775 FPS with 1½-2" 5-shot groups at 100. Then I shot them through my A4. Legit FN 20", 1/7 A4 upper, stock milspec lower, TA31 ACOG. Holy shit those things were scary accurate through this rifle. About the same 2775 FPS but it was holding better groups at 100 than the bolt gun with a 20x scope. Sub-MOA with a stock A4 and an ACOG. I didn't know this thread existed or I would've written down more data and taken pictures. I found it by googling who made the bullets for the AAC 77gr OTM. I definitely plan on buying more. |

In general my stuff pretty consistently prefers their 75BTHP loading to the OTM. I have some SMKs on order though and I’m optimistic. For the price this stuff is hard to beat. My higher end barrels routinely shoot this stuff sub-MOA.

Hopefully Jman is looking into the split cases. There’s definitely enough of them out there that it’s an issue to look at from an optics standpoint for the company. Supplier issue for the cups they use for forming or their forming process?
