The Wonder Wads I use are "dry", but no doubt are lubricated with something-perhaps impregnated with Wonderlube? I don't know how important it is to use a pure lead projectile (as opposed to some harder alloy??). The pure lead bullets I used in the .45/70 were cast originally to use in a fast-twist .45 cal. ML rifle, and I just had to try them in the .45/70 too.

My .45/70 is a Ruger No. 1, and after cleaning it following the test with BP, I thought "I wonder if I can use a charge of smokeless to get the same performance without the dirt?" Since I had just used up the last of my IMR 3031, I tried IMR 4064 instead, and it seemed to work OK-accuracy was acceptable, and I am sure that 457122HP (Gould-type) bullet at 1350 FPS MV would be a good deer load out to 100 yards or so.

I do have one 400-grain Barnes Original semispitzer load for this rifle that produces 2270 FPS MV, but it has such horrendous recoil that I would only use it for BIG BEARS! (58 ft/lb.)
