This information probably won't apply to a lot of you, but surely there are a few people out there, like myself, who like to fire unusual firearms.
I stated on the forum a couple of months ago that one of my sons and I had bought a little German, tip up stalking rifle in 8.15X46R caliber. Due to shortages of everything that you need now days, I couldn't find a die set, in this caliber. I started to build a set of forming dies and was looking through my two buckets of odd and mis-matched die sets. I learned years ago that if you were a wildcatter or experimenter that you should never get rid of old junk dies. I couldn't find anything in the junk containers that would help me out, so I started looking through my good stuff. I ran across a 3 die form set, for .22 High Power. I took the form die #1 and ran a 30-30 case through it, and low and behold, it looked like a 8.15 case. I necked the case mouth up to .308, trimmed the length and I had a case that needed very little fire-forming. I necked up to .308 because 8MM is one set of dies that I don't own. I have an old Herte'rs universal die set, but again, I didn't have a 8mm neck sizer. I honed the 308 out, put in a bigger expander ball ,reworked the seater button and I then had a 8.15X46R reloading die.
I'm still in the market for a good set of dies.
