What I have heard is that the Valkyrie is not stable with the larger bullets.
I am in the same boat as you.... Where to next??
Yeah, from an accuracy point of view, the .224 seems to fly supersonic and fairly flat out to 1200 yards but that’s with a 40gr bullet.
350 Legend? For something a bit closer in and lower recoil that the 450 Bushmaster.
Case is based on a 556 case, just opened up to 9mm (357). MIGHT feed out of modified AR mags? Might have to modify the mag feed lips. Straight walled case will affect mag capacity too?
