I am thinking of sending my 50cal Investarms flinter off to be relined (Have to many 50 s ) and was looking at my Lee 45 colt mold ,it drops at 380 and has a OAL 0.929 . Targets to 100 yds and small game /plinking was the goal and wondered about best twist for accuracy in front of 40-50grains of OE 3F ,maybe some one has a good guess ,I don"t /Thanks Ed
