I run straight wheelweights for 45, 38, 9mm. This saves me so much in expenses I can always have a supply of commercially cast and jacketed bullets on hand if I need to soup up my loads for matches with minimum power factors. I also run staight wheel weights through my 30-30 using a Lyman 311041 170 grain gas check mold, at jacketed bullet speeds. I use the straight ww pistol bullets at steel challenges, bianchi shooting, and a whole lotta practicing. The cheaper I can shoot, the more I can shoot. I have yet to run into a leading problem with any of these uses.
A slow hit beats a fast miss.
