So far I've only loaded for the 30-06 and 270 using RCBS dies and I didn't put a crimp. I am now looking to get into loading for lever action 30-30 and .35 Rem. and from my understanding these rounds need to be crimped. I have been happy using the RCBS dies but are they good for crimped rounds too? Would I be better off with a different brand? These are both rifles that are used for short range deer hunting so I don't want to get too fancy with competition dies or anything like that.
