I've tested three loads for my lever action rifle. A 150 gr Sierra FN propelled by 28.7 of IMR-3031; a 150 gr Sierra FN propelled by 27.7 gr of H335; and a 150 gr jacketed RN in front of 26.5 gr of IMR-3031. I tested all three against factory loaded Federal Power-Shok 150 gr soft point FN projectiles. The powder data of course is a trade secret. The factory loads far outperformed my loads. Of the three hand loads, the 150 gr jacketed RN with IMR-3031 did the best but still woefully outperformed by the factory loads. Any thoughts on this?
