A couple weeks ago I popped the top on a still-sealed cardboard can of mil-surp H4831 and went up to 62 grains with the 130-grain Hornady Interlock Spire Point in a 22" barrel Winchester Model 70 Classic. Average velocity was 3159 fps, without any moly on the bullets, and I could lift the bolt handle easily with the little finger of my right hand.
