I started casting for my .375 JDJ rifle with Lee's 379-250-RF bullet. It is designed for .38-55 loads and is plain base. When I ordered it I guessed at which nose punch to use in my Lyman lube-sizer. Guessed wrong so I'm asking if anyone here knows which nose punch is the right one. Lubing with Carnauba Red and filling both lube grooves. Sizing to .376".
Anyone?
