Myg30, Thanks for the reply.
Well i have made some progress. I bought a bunch of 32-20 brass, then sized em down to 25-20 with RCBS cowboy dies, loaded some FP gas checked 72gn .258 bullets that I cast myself. They soot decent groups. I am having to shoot as a single shot right now. The cartridges wont cycle properly from magazine to chamber. Someone put the wrong RH cartridge guide it. the cartridges are really loose on the carrier. Sometimes the upcoming round will eject along with the spent casing. So thats my new project. Finding a Right cartridge guide for a 1915 Winchester model 92 25-20 or 32-20. I've spent many hours on the internet and the ph trying to locate one. I would take one that is damaged , worn out or broken. Something a could use as a template to create from scratch. I wonder if anyone has ever 3D printed something like that. Holler back if you got any ideas. I'm in Knoxville.
