Tin and Wheelweights
IronKnees, you stated that you use 282 grs. of tin solder to a pound of wheelweights, that comes out to about 4%. You don't need to use that much. You will get better results by using 2%, 140 grs.. Assuming you are using 95-5 solder, I would use about 150 grs. per pound of ww. WW contain about 2.5% antimony and .5% tin. If the amount of tin exceeds the amount of antimony the bullets will age soften, so the amount of tin added should not exceed 2%. After casting I aneal my bullets, by placing them in a 350 deg. oven for an hour, then turn the oven off, and let the bullets cool to room temperature in the oven. This makes the bullets more ductile. You will get nicer mushrooms and less weight loss. 8)
