I have the RCBS inertia type (hammer) puller and I can pull 50 caliber bullets with it, but I have to disassemble it and hand-feed the 3-piece collet type chuck over the case then reassemble and whack away. The specs say the puller is good for up to .45 caliber so I guess I shouldn't complain. The specs on the other brands' inertia type bullet pullers are the same ...45 caliber max.
What about the collet type pullers that you can mount on your press? RCBS and others have collets for 50 caliber but all brands say "for jacketed bullets only". What if I don't care if a lead bullet is damaged or not? I'll just melt it down later anyway ...will these pullers work for non-jacketed lead bullets if I don't care about damage to the bullet? I'd like to come up with a bullet pulling solution for the case when I have made a reloading mistake ...I'm careful and haven't made a mistake yet, but it's good to be prepared.
