@rigbymauser This is GREAT. This is precisely the conversion I have been wanting to do. 458 WM performance in a leveraction actually rated for the pressure. If you would be so kind, I have a few things I would love to know from the only person on the planet that I know has done what you have done.I had a gunmaker here in Denmark to make me a .45-100 leveraction out of a 1895 Winchester Russian rifle. It took the 2,6inch case. The rim had to be lathed down. It shot 400grain Speer bullet at 720 m/sec. I had 3 + 1 in the magazine. The gunmaker did have his challenges to make it work he felt he became married to the project....:LOL.
1. Does it feed reliably? What mods were needed to make it feed?
2. Why did you modify the rims rather than inlet the bolt face?
3. How many will it hold in the mag?
4. What is the max cartridge length?
5. Have you shot 500gr bullets in it? What velocity? What powder do you use?
6. Could you post a pic?
Thanks for any info you could provide, and congratulations on being the first to do a great conversion.
