It only matters on the sideplate side, and if you do glue in a bit of wood to smooth it back out, if you "age" it well enough, you'll never know it was there. :wink:
Actually, on second look, given that your barrel appears to be sunk in the stock well past halfway deep, when you cut down the top of the fore end to half of the barrel (or less), you'll be able to round that little corner back out just fine. :wink:
