Pretty tasty koolaid, I must say. I don't always cheer every new offering. I never saw, for example, the need for a .224 Valkyrie. And I won't need a 22 ARC. My 5.56 does plenty for what I want it for but then, I am not LR shooting with it and trying to squeeze every last bit of fps out of it.
And I don't think I need a .300 PRC either. I have enough .308s and didn't feel the need for a 6.5 PRC. But the 7 PRC seemed to fit just right, so far.
I am also a firm believer in recoil management. Getting hurt makes no sense, at all.
