I am thinking about rebarreling my old 1986 Model 7 KS in 7-08 to a 6-284. I started to do this several years back then my gunsmith died of a sudden illness. As I remember he said he used a Hart #3 contour as that was as large as a contour as the original stock could be opened up to. After measuring the stock and looking at the barrel contours it looks like he was correct. Has anybody rebarreled a Model 7 KS to a larger contour than the original and if so, how large can you go? Thanks. Tom ???
