Taking your cast boolits and swaging them in a swage die is very easy and by all accounts should aid to the accuracy potential you guys might be looking for from your PC boolits.
The challenge is typically these swage dies are of a nominal diameter appropriate for jacketed bullets. For example a 44 cal swage die is typically about .4290" for jacketed bullets and I would imagine you guys would be looking for a 44 cal cast boolit to be about .4310" in diameter so swage dies where not really of much use to the cast boolit shooters.
Well I had been doing a bit of research on the new PC ventures and think I might have something that may be worth a try to a select few that are interested. I have been making swage dies now for many years and on occasion I get a die that finishes too big in diameter after final polish and lap, I can not offer these dies to customers that wish to make jacketed bullets as they may be a half thousandth too big but these dies may be perfect to the cast boolit shooter that wishes to swage their cast boolit before powder coating (and potentially after too) for more consistent boolits and greater accuracy potential as well as a perfect hollow point too!
I have had customers swage their lubed cast boolits and do very well in the national level shooting competitions but have yet to see anyone swage there cast boolits before or after powder coating them. I would certainly think there is potential for great things coming from a swaged lead boolit.
Here is a look at a .4305" swage die I have and some 240 grain 44 cal cast boolits I reworked in this swage die. I simply painted the three colored swaged boolits to give you all an idea of what they could look like.
I have a few of these dies offered right now on the swap and sell forms.
Good shooting!
