I seem to recall earlier in the thread Rudy stated he would be using Mag-Tech brass shells. These would require oversize wads, so as long as wall thickness is safe would allow for a good bit of honing without an adverse effect on pattern. In fact guns purposely built for the brass shells were built with oversize bores. Many of the older Lefevers, Parkers etc will be found with these larger bores, & not necessarily because of honing.
