if you go to castboolits on this site and look under the heading, a couple of pics of old school boolits. newton posted a picture of a bullet design i had made into a mold. now we found out it is not a new design but was made during the civil war. the front is a bore rider and the back is shaped like a attached round ball. it is .50 cal and the back part is patched and the front rides the bore. it weighs 535 grains and is extreemly accurate. a real freight train out of a fast twist muzzle loader. my barrel is 1.28 twist. 36 inches long. .50 cal. steve brooks made the mold for me.
