Hey all, I’ve been reloading for a few years , but always with jacketed bullets. I’ve recently decided to purchase and load some lead bullets. I’m looking at Oregon trails laser cast in .38 special , 158/grain RNFP and 45colt 250 grain RNFP and some 300 grain 45/70. Question is, if I buy these bullets, do I still need to size and lube them. They have two black rings on them and crimp grove . What about gas checks ? Are one of the lower rings a gas check . I am hoping if I’m buying bullets and not castIng them I have bullets already to go and do not need to do those steps.
