I too have owned & used a Lewis Lead remover for over 35 years. If you are a serious revolver shooter you NEED to own one! Inexpensive, efficient, quick and safe, they will get the lead out 1,2,3!

For plinking a and target shooting I like 158 grain RNL bullets which are very accurate, and reduce the leading to almost nothing. If you still are getting significant lead build up with them, then yes I would check the timing.
