I picked up an M95 straight-pull chambered in 8x50R a few months back, and I’m to the point of making brass for it. I have a set of 8x50R dies from RCBS, and have followed the procedure mentioned to make brass from trimmed 7.62x54R brass, but for some reason the rounds (unloaded at this point) won’t chamber without tapping on the bolt handle with a hammer, and I really don’t want to do that.
I will be making a chamber cast this week to confirm the chambering, but the only thing I can think of at the moment is that I’m using Norma brass instead of the PPU that most people are using. Is there a known difference in rim dimensions between PPU and Norma 7.62x54R brass? I did grind down the rim a bit, but it didn’t make much difference (took it down to match the 14.00 mm diameter of my surplus 8x56R rounds I’m using as a rim reference).
Suggestions? Anyone have similar issues with their 8x50R M95?
