Hello all. I have some questions about reloading the 7.62x54R cartridge. The rifle is a Mosin-Nagant 91/30. The bore of the rifle slugs out to .312. Unfortunately the pickings seem very slim as far as .311 or .312 bullets go. So far all the information I have found on the internet for published data is for the .308 bullet. I have been away from the reloading hobby for about 15 years. My experience has been with .223 and .30-06. Right now we have 120 rounds of PPU ammunition with 150gr. soft point bullets. I measured the bullet as close to the case mouth as possible and came up with .310. I have been told that the PPU brass is boxer primed and reloadable. The few people who I have spoken to have said they use bullets meant for the .303 Brit round (.311 or .312) and have used powder reccomendations for the .308.
My questions are as follows:
1) Can anyone recommend a current reloading manual that has listed loads with the .311/.312 bullet ? I have looked at the powder manufacturers load data on their websites but they only list make, type and weight of bullet. No diameters are given.
2) Is it o.k. to use load data for a manufacturer's .308 bullet as long as the .311 bullet is of the same weight and type ? I would start with minimum load and work up from there. I have in the past used load data from one manufacturer for another's bullet of the same weight and type after consulting the information from two separate load manuals (.308 diameter match type bullets - these loads were for an M-1 Garand). I always started with the recommended lowest powder charge and looked for any signs of excess pressure. These loads were very modest due to the operating system of the rifle. The rifle always functioned normally. However I didn't have to substitute a different diameter.
All answers are appreciated.
