I'm new to the forum and I thought I may as well dip into the well of knowledge right off the bat. I just bought a Win M70 in 375 H&H and would like to work up some loads for it. I will be shooting 270 gr Speer BTSP and will be pushing it with RL 15. It seems like all the literature shows it at 2700 +/- which is right where I want it. What kind of info have you got?
