I'm doing a bit of reloading and I'm having a hard time finding info using the components I want to use. I'm loading for the 7.62x54R using: new PVRI cases WLR primers IMR 4320 powder Barnes TSX 150gr. .311 bullets with a COL of 2.990" I tried this combo with 48.0 gr. of powder and didn't quite get the velocity I was looking for, but accuracy was good. I've tried to piece together some information from the web like handloads.com, Steve's pages and such. I'd like to try something like 49.5 gr. of IMR 4320 and see what I get but I cannot find any published data. I did find a person who's favorite load using a 150gr. bullet was 49.0 gr. of 4320. Steve's pages says I can max out at 51.0 gr., but that's for a .310 dia. bullet. Anybody have any thoughts..?
