ok im making a mold for my martini henry mk 4 witch uses a .470 480gr bullet the only choice of alloys is wheel weights but i need 20-1 lead/tin
it has to be close enough to 480gr and .470-.472 as these guns where made for one load and the sights are not adjustable (only for yardage) how close will wheel weights get me to this if i use 20-1
