I have an M95 in 8x50R. It has a good bore and I would like to find an accurate load for it. I don't have any molds in this caliber. I fired a few rounds in 323. The original bullet was, I understand, .324. However, the grove diameter, I slugged at .329. I do have some grafs J bullets for the 8x56R in .329. However, the neck of the fired case measures 327 ID. I know that if the neck is too tight in the chamber it will dangerously increase pressures. So how tight is too tight? If a cartridge loaded with a .329 bullet chambers easily, is that ok?
