I pretty sure I ruminated about muzzle loader alloys awhile back. Well, today I tested them out. I’ve always hated casting pure lead because it seems to not want to fill out a mold as well as my more used alloys. Awhile back I cast up some Lee .58 cal Minies out of pure lead and some 20:1 lead to tin. The 20:1 cast much nicer and easier. The Lee has a daily thin skirt so I figured it would expand and fi up the bore.
Well, apparently today wasn’t a very good rifle shooting day as the groups below show. But the important thing, to me, is that the 20:1 bullets grouped roughly the same as the pure lead and as you can see, no keyholing meaning that the skirts are obturating and filling the bore. This will require some more testing on hopefully a better range day but shows promise for sure!
