All-
Thanks again for all of the info on my "Casting for Dummies" thread, I have a few more rookie-type questions. Specifically dealing with leading; not that I have any grossly disgusting problems. Nothing that affects accuracy, (@ least as well as I shoot a handgun), and nothing that a few J-bullets, (I know that is a dirty word around here) won't push out of the bore. However it is enough to be annoying, particularily when I forget to bring a few J-bullets to the range & I'm stuck cleaning all of that out. Is leading a function of velocity, or bullet hardness, or both? Is a gas check necessarry? Is that the end all to the leading problem? As to bullet hardness, and please correct me if I'm wrong; I understand that adding antimony to the mix will harden it. Too much antimony makes brittle bullets. Further, heat-treating will harden a bullet, will it make it brittle? The Lyman handbook has you heating your bullets in a 450 degree oven for an hour & then quenching in room temp water; wouldn't it be easier to drop them straight from the mold into a 5 gal bucket to quench them? One final question as to alloy, does the tin do anything other than make the lead "flow" better? Again thanks for all of your help on my last thread, and thanks in advance for your responses to this one.
