Got a new .375 RB 2cav yesterday and immediately tried to cast some up.
Admittedly, I am using "iffy" alloy that I won't use for Lubed Boolits, but will be just fine for Slingshot Ammo, but MAN I have NEVER had RBs end up so wrinkly.
Also admittedly, I only did 20 on a cold mold, so I'm guessing there just wasn't enough time/contact with melt to heat the mould decently?
I've never used a mould with such small cavities before so I've never seen this...
