I haven't decided to buy the 450 yet, I'm still researching it so I'm looking to see what the best reloading setup is. The only 450 BM dies I have seen are the Hornady's which include a seperate crimp, is there something wrong with the Hornady crimp? All my reloading dies are Lee, so I'm not familiar with the Hornady stuff, I really wish Lee would hurry up and make some. I contacted Lee about using a 284/45 COLT combo, obviously the 45 colt would not work for sizing as the cartridge is tapered. They said I could try to neck size, but may not work in the semiauto. Any thought or has anyone tried using the 45 COLT (or 454, 460, 45 ACP) Lee crimp? Wouldn't that be easier than modifying a 45-70?

That puts the crimp right at the case mouth, Too close for head spacing. Then take .05 off the top of the crimp ridge to move the crimp back from the case mouth .05 and narrow the crimp to about .05. I can't measure the crimping ridge. But, it apears to be about .10
Would .05 back from the case mouth be enough for head spacing?
Would .05 be a wide enough crimp?
