For 45acp you can cast lead bullets. I rarely use jacketed in my 38s (only in my comped custom revolvers), 45, even 44s. For light loads you do not need hard cast bullets either.long haul but will need to wait until i can afford to get a complete set up or buy piece by piece while theyre on sale. Complete side bar, i pour my own lead rounds for my ruger old army (6 cavity lee molds) and was curious if anyone here has experience with pouring copper projectiles for their own bullet making?
