  1. I'm hoping you put a quicker twist rate on it in the shorter barrels/ I know the 300BLK with a 1:5 twist is way more accurate and the spin cavitation is more effective. It's the 1 downfall I see in the .338 ARC as opposed to 8.6 blackout/ I't's the spin cavitation that does the damage to the target with subsonic loads.

  2. Why keep coming out with these new rounds . Put the tech into all of the calibers we already have , They are just salesmen trying to get us to buy more Rifles / pistols . Just my humble thoughts

  3. Every time I build the newest caliber, a month later a new one comes out, I have to keep checking all my barrels to make sure I m using the correct cartridge and calibers.. because half my 223/556 parent case cartridges will fit… and ammo prices and of course I need to buy enough for the end of the world in each caliber, it’s getting exhausting 😂
