I'm with much of the crowd - H4350 is where to start powder-wise, but after shooting 139, 140, 150, 154 and 160gr bullets, the semi-odd-ball 145gr Speer is the one that really stood head and shoulders above the rest in my rifle.
Take a look in the latest Speer manual. They show some very good velocities with several powders but I've been working in the dark, so to speak with RL17 and getting some very good speed with that one. Speer #15 has data using RL17 and it seems my loads were not all that far off. Works great in a Winchester M70 and I'll soon be doing a serious test with a custom Mauser that shows high pressure signs way before the M70 or Ruger #1A. I'll be making those loads later today once it warms up a but. It's a tad chilly in the AM and there's no source of heat on the shed where I do my reloading. I'll probably use the 160 gr. Speer hot core as I'd like to use that rifle on an elk hunt. Paul B.
