I use pure lead, I have a small selection of molds for my 45-70 and I use w/w, for
the savage I went to pure lead because I like the expansion. I did recover some 405's and one 520, the 405 was quite wide, the 520 is the size of a 50 cent coin
and weighed 505 gr. Now, these were shot with a dirt back stop. I can't wait till muzzle loader season. Dan
