Anybody have any data for the 7.7x58? I have some pulled 7.62x54 .310 dia. 150 gr. (Actually they range from 149 to 150 gr.) boatail spizers and would like to use Reloader-15 if possible (I have a ton of it!!).... As well ive heard people using the military 7.62x54 powder and reducing the load 10-15%... Any thoughts, suggestions?
Ive found that RL-15 is used in quite a few old mil-surps and im sure theres gotta be a load out there.....
