Forming & Trimming The 577/450 Martini Henry Case from 24 Gauge Shotgun Shells (First Attempt)

Today we start the adventure of reloading for my Martini Henry. Trying not to brake the bank, we are converting 24 gauge brass shotgun shells by necking down and trimming. Today I figured out a way to trim the large case with tools I already had.

Thanks for Watching.
