I just got a Rock Island 45 acp and had some reloading questions. I have and reload 45 long colt. I use a 230 gr. round nose lead bullet and have several of them. My question is can I shoot the lead round nose bullet for the 45 LC in the 45 acp semi auto gun. I had a guy tell me it would shoot fine but he was concerned about the Lead bullet dirtying up my gun and I should use a jacketed bullet ??? I don't mean to be cheap but if I could use these lead bullets in both guns it would be easier. Any input would be helpful.
