I have several rebores and I have spent countless hours on the phone mentoring under Wayne York, Jesse O, Al Siegrist, Gene Pratka, Mike Bellm, Danny Pederson, Randy Selby, and Norm Johnson. I'm still no expert. .100" wall thickness at the muzzle is the general rule of thumb as there's alot less pressure there than anywhere else in the barrel. I've also learned from those men and first hand that every barrel I get rebored will get at least .700" cut off the end and recrowned. My best shooting rebores have 1" less barrel length and are truly the most accurate rifles I own.
