Leading

Or one of them anyway, look at the Keith Loads in Taffin Tests

Let us know how it works out.

Mshaw;
Last year I bought a SBH 7 1/2 out of nostalgia. I had when I met my wife in Montana in 1968. I eventually traded it off and got seriously into 44 Spl's. But, I eventually had to have another. Mine was made in 1076, so it's close to yoyurs in age. I cast my own bullets in Lyman 429321 persuasion (250 gr. Keith) out of wheelweights mixed with 25% pure lead. My load is AA #9 at slightly less than Taffin talks about in the Taffin Test article referenced above. I get absolutely no leading and very good accuracy. Bullets are sized to .430. I have had no leading problems with any of my 44's or 45's since I started using Lee Liquid Alox or Xlox. And it's more fun than wrestling with a lube-sizer. There are excellent videos on Youtube by ssfliberal showing how to use it. Try it. It might help.

Mshaw:  I've run into three problems with some commercial cast bullets, all of which can lead to leading.  First, many if not most are cast too hard.  Second, many are bevel base.  Third most are sold in one or two "standard" diameters and may not be suited to your revolver's chamber throats.  I suggest that you start by measuring each chamber in your cylinder and choose bullet diameter equal to or 0.001" larger in diameter than the largest throat, as long as that diameter will seat when loaded in your brass.  Then, select flat-based bullets, no harder than necessary for the velocity you wish to load.  For example, BNH of 12 to 16 should be hard enough for velocities between 1100 and 1400 fps.  For reference, the frequently mentioned "Lyman #2" alloy will give about BNH 15 and should cover most magnum revolver appliations.  I hope this is helpful.  -Ed
