Swaging and shaving cast boolits during seating has been an ongoing, unending problem for me using my own cast boolits. My alloy is soft compared to the commercial cast boolits I used to buy which didn't have this issue, I figure mostly because they tend to be 18 Bhn as opposed to mine which are around 10.
I need a powder through expander funnel that will expand, not just flare, but expand my cases. I'll be loading 9mm boolits that are sized .356 and .357, and 45 ACP boolits sized .4525 to .453.
It has to be a powder through expander. I don't have a spare station for an expander only die. Is there anything available that does this?
