I recently mixed up a batch of alloy consisting of 94.3% lead 3.74% antimony & 1.81% tin. This was figured using the lead alloy calculator located on this site. I cast a batch of boolits using various molds/calibers to try out. With the Accurate 310c 45 mould boolits came out at 308 grains and were water quenched. Sized accordingly and lubed with FWFL they shot superb in my Ruger Bisley loaded with H110 and a federal primer. Same alloy, quenched and lubed with a BRP 454424 also shot very well in the same gun with both green dot and Hs6. Now in my Lipsey's 44 spl it was not so good. The old Skeeter load has shot well in this gun before using 50/50 alloy. I know this gun can shoot. Having changed several things being alloy lube and powder it could be a number of things. This gun seems to like 50/50 better. I will cast some more BRP 429421 boolits 50/50 and lube with FWFL and go back to the 7.5 grains of unique. This past session I had tried 6.0 grains of green dot because I had it and heard good things. May still shoot with green dot but at 50/50 alloy. Any comments on what makes a gun prefer one type of alloy over another? I may add I had zero leading in both guns with the alloy used as well as a Super Redhawk 44 mag that also shot well. Can it be the lower pressure 44 spl needs a softer alloy? Boolits were sized .432 as cylinder throats measure .431. Thanks!
