This isn’t really anything new, just a different technique for making 350 brass.
I read about forming 350rm brass from any magnum brass. The problem is the store bought “case forming die” does the sizing in one step resulting in a fairly high failure rate. So I had an idea for a forming die.... I made a die that takes replaceable shoulder/neck inserts incrementally tighter. I made 4 inserts to really ease the process. I have not lost a case using this setup.

This is 300wm and a 375 H&h range picked up brass...




Next issue was hacksawing necks off became a pain so I built a crude cutoff saw that’s fast and fail safe.
