That is exactly what I did to my 111 Long Range Hunter last weekend. I used a utility knife to cut the barrel to the correct contour because the heavy sporter Shilen was a slightly different contour at the end of the stock than the heavy sporter that came factory. I did have the dremel get away on me when I did under the barrel, and scuffed it a little. But overall this was the easiest way I could see doing it.
