For an alloy I like seven ingots of clip on WW, one ingot of Linotype, and 2% of tin. I had a sample analyzed at 92.7% Pb, 4.5% Sb, and 2.8% Sn. it may be unnecessarily hard but I like it and it works.
Fred has posted pictures of my Krags in the past few years. You may search my pitifully few posts and find them there. This year I shot 2,200 Krag shots, all five shot groups, deliberate fire iron receiver sights. Maybe old school but I think it's fun and rewarding.
