I have the 125 pounds of lead pipe my neighbor gave me. I just received 6 bars of 70- 30 super-hard from Rotometals. I also have a 50 pound lead pot and a large ladle.
Each bar would be 1.5 pounds of antimony and 3.5 pounds of lead. If I buy a 1 pound roll of no lead solder and cut it in half that's .5 pounds. Mix that with 19.5 pounds of my lead pipe (after I smelt and clean it) and I come out with 25 pounds of 92-6-2.
So how accurate do I need to be on that lead? If the weight floats from 18.5 to 20.5 is that going to make much of a difference in how it performs?
This is all handgun, 40 S+W, 9mm, 45 colt,38 special, 357 magnum and some 405 HB 45-70. Fired in handguns (except the 45-70), but also in a 45 colt and a .357 rifle.
This is also is going to be made in 25 pound batches, so the final products will be mixed when they hit the casting pot.
