I've been casting for some time, but I've only powdercoated my wadcutters. Had a few kids since my last casting session (it's been a while) and I was hoping we'd see some RN slick side molds specifically for powdercoating, but it certainly doesn't seem like it. So, I guess I'll use my Lee 125gr RN mold. Are there any issues with heat on a full auto sub gun that might negatively affect a powdercoated projectile? I wouldn't think so, but I figured I should ask before I cast a ton of them. Thanks!
