Dip-Casting Bullet Weight Experiments

[Gunlaker]

Wayne, I have never seen this effect personally. When casting for the recent match in Phoenix I cast 400 bullets in batches of 100. I generally don't use the first few bullets from each batch as they are light, but appear perfect.

All batches had the same average weight. Three were within +/- 0.3gr and the other was +/- 0.4gr.

I'm using a Lee 20 lb furnace and dipping. I make no effort at stirring, and keep the ladle submerged, except the spout itself which I keep protruding from the melt to prevent a buildup of "dross". This generally makes better bullets for me.

I'm no metallurgist, but I was under the impression that our alloys of lead and tin should exhibit no stratification. Is this incorrect? I can't find any references anywhere.

thanks,

Chris.
