years ago i read that alot of the buffalo hunters would put a silver dime in their lead pot when casting. so i bought some 700 degree silver solder and put about a 12 inch piece of the silver wire in my lead pot. the results were more shiny bullets and they came out of the mold super easy. in other words a better cast bullet. the buffalo hunters were right. i knew two brothers who where pushing their 45 cal bullets to 2200 ft per sec. the pointed nose would bend over. they added a little silver solder to the lead and the bullet never deformed after that. they won a lot of 500 yard matches. just a thought from a 80 year old shooter.
