roll crimp ?

[Paul Harm]

I found the 3/8" from top of shot to top of shell a bit too much - a lot rolled over. Or it may be because the diameter of the punch is too large - it makes a really tight fold. Either way, I have a second punch that has a plug added on to make the punch thicker [ at one time I was loading 2" shells ]. Because my roll crimp shells made by spinning the end are thicker; I was having trouble with the Mec. So I'm going to turn down the diameter from .640 to .550 [ what a paper shell measures inside when roll crimped with the drill press ]. Maybe it'll also work with the plastic shells. Paul
