Hey All,
Quick question, I am interested in casting and polymer coating, I have already sussed out how I would copper coat, but would really like to powder coat and see the differences in how fast I can push rifle projectiles before leading. HOWEVER.
The only 243 moulds for cast lead have a number of lube grooves, which makes me wonder 2 things.
1:Aerodynamics, how much does it disrupt boundry layers and create inaccuracy.
2: Leading, yes it helps catch any blow by and make it usable energy, but could it lead to excess leading?
3: What advantages other than "Holding lube" can you think of, particularly when you are only holding lube which we don't need anymore.
Anyway would be interested in hearing what people have to say. I am really interested in casting some things.
