I’ve cast and shot thousands of the Lee .311” 160gr Pt.GC bullet! 6cav, 2-cav and older 1-cav molds.
Never considered to use it to hunt with.
My .300BO upper feeds the Lee .309” 150gr FNGC perfectly! At 1,750fps, for .300BO purposes, it’s perfect!
I typically used COWW, +2% 95/5 lead free solder. From a .30/30 @2,200 FPS, @158gr, they equal or exceed factory ammo.
I’m now powder coating...
