That same old completely irrelevant barrel length still being used is just stupid. Nut up and show what is will do in the AR barrel lengths it is targeted at.

Meh. 6.5 Grendel is so similar it’s not worth the change. Plus, 6.5 Grendel I am assuming will work better out of shorter barrels. For that, I am out. Until they release ballistic comparisons between the Grendel and the ARC out of a 12.5 inch barrel.

It would be nice if they would tailor a load for 12-16" barrels. Pistols and carbines are a thing. |

Wolf steel case 6.5G is the bees knees for plinking. As I am reading more about the ARC it appears that a specialized magazine will be needed just like with the Grendel. Honestly it seems Hornady is stretching themselves thin by coming out with all these new “innovative” cartridges without the backing of other companies. For example my 6.5 PRC. What is it? Long action? Short action? Mine is a short action. Some are long. And if I handload anything over a153 grain bullet it won’t even fit in a short action mag. It’s really a wild cat cartridge with Hornady branded on it. With that said, the ARC isn’t innovative. It’s based off the 220 Russian with the shoulder set back and with a reformed shoulder angle. Ballistic wise the Grendel has more energy but slightly more wind drift. Now if Hornady could actually get backing from other companies like magpul to make specific magazines for this cartridge I might be in but that’s highly unlikely when we have 100,000 different AR-15 platform cartridges. I wish Hornady the best of luck with their ARC but the Grendel is too similar for me to change. TLDR: the ARC is the Grendel’s sister cartridge. Nothing innovative to see here. Ballistics are so very close to each other |

I'm sticking with Grendel for now just because of deer though. |

Until they release ballistic comparisons between the Grendel and the ARC out of a 12.5 inch barrel. This clearly isn't a round tailored to work well with short barrels. I will be interested to see what barrel options become available and what their life expectancies look like. As well as the mag availability maybe expanding to companies like Magpul. ETA: See 21 minutes, he claims it does pretty good in shorter barrels.  6mm ARC: Overview |

I fucked up and got on the .224VALK train early on and that shit turned out to be a mess. So I sold that shit off and re-barreled the upper the .224 bbl was on.
I think I'll sit this one out for ~18 months to see how it pans out.... if its good then I'll put one together. |

I wonder how it compares to the 6mm PPC that Olympic was chambering back in 1991. It was my first AR-15.
IIRC, it fired the 85gr Speer at 2700fps from my 16" barrel. Tony Rumore Tromix |

So it’s only “better” than Grendel in that you can find a wider variety of boolits.

The Brownells video is better. It looks like it does have a shorter COAL. So if that is the case with similar performance. The ability for a poly magazine to be introduced. This might be worth it.
Then it is just the bolt face concern. I would wait until inexpensive ammo is brought to market though. Hard to compete with the 6.5G wolf. |

If you didn’t watch the videos one thing this Apparently addressed is that the Grendel struggled with the right bullet/velocity combo. This apparently allows a better combo. |

I don't hate the Grendel mags they have bee good for me. However, the lack of options has had me scratching my head for a while. |
