lead for me
Lead is cheaper especially if you reload. I shoot only lead. That said, jacketed bullets are much harder than lead as they are made of copper, which will cause much more barrel wear on the lands in the bore. Many tears ago a gentleman used a micrometer to measure the amount of wear, and in the older guns it was significant, but today with the modern steels it is not as much. Hence, you do not need to be so concerned with modern revolvers because the velocity is low. Now, in rifles, that is a different matter as the velocity is much greater and hence, even with modern steels the wear is significant, especially in the belted magnum rifles with velocity above 3300 ft per second.
