Too hot and the lead would dangerously vaporize -- a very bad thing. Good point about the conductivity though. Well, I was just tossing out ideas :)Gyrogearhead wrote:A propane tourch was the first thing I tried in dealing with my 50# ingots and I quickly found out the thermal conductivity of lead is high enough you end up heating it for what seems like forever before the spot to which the tourch is applied begins to melt. Of course if you used and Oxy-Acetelene tourch with it's much higher flame temp you would get quicker results but then how much does the gas cost???OldCannon wrote:Wouldn't a blowtorch work?

Re: Bullet casting question
YES! I have this. Great book! Not directly related to casting, but I also recommend "The ABC's of Reloading".AndyC wrote:There's also a highly-recommended legal PDF copy From Ingot to Target: A Cast Bullet Guide for Handgunners

Re: Bullet casting question
Ah, that explains a few things. I don't often get wrinkly bullets, but about one in 30 I do. I reckon adding a tony amount of tin won't harm my bullet performance. I'm always concerned about getting the minie skirt expansion sealing correctly though.AndyC wrote:The guys made good points.
Also, bear in mind that lead by itself has a very high surface-tension - with the result that it won't fill out the mould-cavities completely, and you'll end up with the classic "wrinkly bullet" syndrome. 1 - 2% tin added to the lead will give you a liquid that runs like water into the cavities and will result in beautifully crisp-looking bullets; you can add tin from things like 50-50 bar solder (50% tin, 50% lead), etc.

Re: Bullet casting question
I will gladly accept all donations of pure, soft lead. My Minie balls insist on only the finest lead
I'm curious about your source. I'm told that there are places that have scrap "xray wall" lead, but I can never find a "Lead Walls R Us" store
