New 6mm Advanced Rifle Cartridge

She's a shooter. Sub-MOA with factory loads; took it out to 1,025 yards today. The 6 ARC is growing on me ... a lot.
I shoot mostly Hornady Black 103gr and Hornady Match 105gr. About to start working up a handload for it here when I have time.
Finally got the X-Caliber 13", mlgs lightweight barrel that I ordered back in March in. Going to try a BFK Mod 0 thermal fit upper and reuse a 12.7" Aero handguard I have on this one. Waiting for Rexus Ultra bolts to come back in stock in the next few weeks and should be in business.
Indeed - MiniFix in 6ARC with a Proof Carbon barrel is the handiest bolt gun in my collection. I can strip it down to just the 3-20x and lug it up and down the mountains like it's no big deal at all.
Or I can load it up with some craziness...
Oh and I'll add, I've now gone through a number of different barrel lengths in semi-autos - from 26" to 20" to 16" to 12". I really think with anything longer than 16" you rapidly hit a point of diminishing returns with this cartridge. Granted, I'm not using commercial ammo, so maybe that'll run better, but my own 103 ELD-X / 105 Hybrid / 109 LRHT loads don't see a significant boost in velocity past 16", at least not the 25fps / inch expectation you see with other rifle/cartridge combos. I just started shooting the 12" and it's crazy how a shorty can essentially perform like an old school full size Mk12.
And here I have a 22” ar barrel on the shelf for a gas gun comp build when the m lol Vltor vis gets released
