RCBS makes a crimp remover that works on a reloading press and Dillon has one that you can mount to a bench (the better of the two in my opinion). It really depends on how many pieces of brass you think you may want to process. If you only plan to do a hundred or so, then the RCBS should work out fine. I have done several thousand rounds with the Dillon and it is definitely my favorite of the two. Both will resize .223, .308 and 30-06 brass. I believe they will aslo remove the crimp from 45ACP and 9mm, just haven't tried pistol brass on either of mine. I hope this helps.
