Brother, I'll tell you this right now. I can already tell where this is going, with this cartridge. I've done the Grendel (BADASS!), then I did the Valk - supposed to be a Grendel-Killer... Wasnt. Still have the SPR gun to prove it. Then the 6 ARC - THAT motherfucker is an improvement!!! Hands down! It really is better than Grendel, if you're after distance, a little accuracy, and bragging rights. One-for-one, the 6 ARC is gonna beat a Grendel for that.
However, I'd HUNT a Grendel over the 6 ARC. Projectile weight, and energy on target. Now, JBMatt just smoked a Coues Deer with his 6 ARC and the 85gr Sierra Gameking a week ago, and I was eating that thing 8-days off-the-hoof, never frozen. 6 ARC works.
Grendel was a game-changer. Then 6 ARC was a game-changer over that one. I think this 22 ARC is another game changer over both of those, within intended purposes.
I have 5 Grendels and 3 of the 6 ARCs to feed. I'm poor, and should start a GoFundMe just for that. I'm going after an 18" SPR Mk12 22 ARC right now, and it'll become a reality - but just to solidify my interest in this one - I've already ordered a scope, mount, and rail for the 12.5" barrel that NOBODY is making yet... But they will. And I'll be ready when it drops.
