Gary Growe in Columbus, IN. is an excellant 700 and 1911 gunsmith and machinist. He does tactical, benchrest, and everything else. He did my trigger job ($30) and a tactical bolt knob ($45). He doesn't always work regular business hours so call him before showing up. His place is on SR-46, just as you leave Columbus. Less than 1 mile off I65 exit 68. Call him at 812-342-6079
I too have been looking for a smith to replace a Sendero 270 barrel with a 30-06 tube but gave up. I spoke with 2 and the prices they quoted for the work was so high that I could have just bought another rifle. The 270 sits all alone in my safe until I find a buyer for it.
