I have always shot jacketed bullets through my handguns. A friend gave me some non jacketed leads to try. They really shot good but it seems like a lot of lead in the barrel. I tried cleaning like I do jackets or rifles......shooters choice....brass brush....repeat...repeat...seems like alot of lead left. Are these shells that much dirtier or is there a better trick I am missing. Until cleaning I was ready to switch!!! Thanks, Doug
