A 123gr SST in my Alexander Arms AR shoots 1/2" all day. 2450fps from a 20" barrel. Amazing performance from a 1.5" case with 30grs of powder (parent is 22/6mm PPC) and it fits the AR15 action. Shoots through deer and hogs with authority. As far as recoil, you can see your bullets hit the target. Your question on the x57 case - It's 2.235, so it goes in long actions. 308 family is 2.0xx.
