hmmmmmm, interestin! ive read everywhere else that the lead is too hard and often wondered why, if it was because the metal was softer in bp guns or the riflings were too different or what they based their declaration on! i know lots of people will use jacketed sabots in the long guns and thats pretty hard ammo! but every time ya discuss it on pistols they yell that its not good to shoot wheel weight lead outta it! why do people say that? i saved up a 5 gallon bucket of wheel weights and have never used any of it because of this! i kept it tho , because i figgerd if hard times fell upon us , anything would be better than nothing!
