I thought about asking this on the current 410 round ball thread, but didn't want to hijack. I've been tinkering with a .410 load for a while. I have .375" cast round balls for my .36 Navy revolver, a can of Lil'Gun, a bag of WAA41 wads, and a grocery bag full of worn out Winchester .410 hulls that were given to me.
The hulls are worn out in that they have cracks in the crimps. My thought was that I could just cut the crimps off, find a good load using three round balls, and roll crimp them or something. I have an old Iver Johnson single shot, and a friend with a Judge revolver wanted to try some. My thought was to not hot-rod them at all, but keep them on the safe side for the old gun. These aren't for hunting or any other practical use, just plinking at the range.
My biggest problem at this point is to try and figure out a simple yet effective crimp. Any advice?
