I have a Winchester M/70 that Randall Redman rebored to .35 Whelen, he is no longer accepting rebore work due to sizeable backlog. Cliff La Bounty rebored a S&W M/27 revolver to .44 Special before he retired, and I have another M/27 rebored by the gentleman who took over Cliff's business. Both the rifle and the revolvers are very accurate and I would not hesitate to undertake another rebore.
