Well, after some casting, heat treating, powder coating, gas checkin’,( not in that particular order), I finally assembled some test rounds.
55 grain Lee boolit, sized to .225”, CCI SR primer, a healthy load of AA2520 ball powder, and I’ll set the final coal when I do the chronograph testing.
I hope they are accurate! The powder load might overrun the alloy,( ww with 2% tin heat treated),but testing will tell the final story!
Pictures to follow,maybe.
