Has anyone had luck with squeezing jacketed .458" diam bullets down to .452" diam in a Lee bullet die?
If so my next questions would be do the old 405 grain 45-70 bullets fit in the mag/ feed in an AR15. Does the extra bullet weight create enough pressure to cycle the rifle?
Michigan just opened up hunting statewide to suppressors and the 450 BM is legal in the southern half of the state but the 458 Socom is not. So now there is a movement (or craze) toward a subsonic 450 BM.
