I did look some so hope this isn't redundant but didn't quite see it. Just looking for a good hunting round out of the Guide Gun 45-70 and whereas I used to use WW cut with lead and Tb/Sn solder to get it to 96% lead, 2% each of tin and antimony, my wheel weight sources have dried up so I ordered some Lyman No 2 and lead from Rotometals.
Presuming 1700 fps and gas checked, before water cooling, I'm getting a calculated BHN of 11.6 with 50:50 No. 2/Lead. Getting tin and antimony at 2.5% each. Originally I had it at 1:1.5 so I had 2% each of tin and antimony, but am guessing the 50:50 would suit.
How do you guys feel about this alloy - and would you quench or air-cool (my presumption is that I brought the BHN up to 18 or so with quenching, but I really have no real idea).
