Using .312" 174gr Hornady HPBTs in my P-14, No.4 and SMLE, my IMR 4064 loads have varied between 39.0gr to 40.0gr (fine-tuned for each rifle). With Prvi brass (neck-sized and sorted for use in one rifle only), this gives an average velocity of ~2250fps. I also tailor the overall cartridge length for each rifle based on the maximum length that will still allow for reliable magazine feeding and closing the bolt easily. Together with Winchester WLR primers, I've had wonderful results using these in milsurp competitions.
