I would like to know if its safe to use lead bullets in my sig P-250 ,45acp for practice. I was thinking of using Silver State 200 gr. fbswc bullets. I would like to use VVN310 powder. Rem # 2 1/2 primer WW once fired brass. I'm thinking of apx 4.0 grs. Taper crimp @.469. Thanks for any answers & happy shooting. Don't really want any hot loads. k&j 223
