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.
I used to buy that same powder from the old Buttreys Grocery store in Bozeman, Montana back in the late 60's in bulk paper bags for .67 cents a pound. We put in Ball canning jars to store it. Talk about the "good old days".....grin!
Yep.
Still had some of those bags until recently when they got so brittle, my thumb would about poke thru the side of a bag, just handling it. I transferred everything into empty powder cans, now labeled with a Magic Marker.
The powder still smells good, looks good and shoots good. No dust or evidence of deterioration.
