I am looking at a .450 Bushmaster or a .458 SOCOM in an AR platform. THE .458 comes with a 1:14 twist rate and the .450 Bushmaster comes with a 1:24 twist. I plan on using cast boolits only in the one I choose.
I understand the .450 B uses .452" boolits weighing 200 ti 250 grains. The .458 S uses .458 boolits of 350 to 500 grains.
I already have .452 mols of 160 g. swc,185 swc, 200 swc and 230 RN. For the .458 I have .350 g. Swc and 450 g.. I am not limited to these molds.
Which would you buy? I doubt I would ever hunt with it but whitetail is the largest animal it would be used on. There is no straight wall case restrictions in my state.
