I called JES regarding a possible 358 Winchester rebore. He advised that as long as he had twenty thousandths of an inch over the bore he could swing it. Just give him a jingle and he’ll either pick up the phone or call you back and give you the run down. Very down to earth guy. I’ve heard nothing but good about his work. I rebarreled a Ruger M77 from’06 to 35 Whelen with a same contour and length barrel. I love it and would do it again. Just keep in mind that Ruger 77’s aren’t light. So, I’d pick the lighter of the bunch and go with that. My 35 Whelen with heavy loads flinging 250’s at 2700 doesn’t kick any more than a stout 30-‘06. Good stock and good recoil pad are everything.
