Is there an easy way to dress a barrel crown?
My son's .270 has accuracy issues. The end of the barrel has a few bad dings in it & I'm quite sure it has to affect accuracy. He has no idea how it got damaged . (I swear the kid takes after his mother, rest her soul). I was thinking I might use a spherical shaped very fine grinding stone. the kind one would use on a Dremel and such. I have them in different diameters. Can I take one that matches the crown radius / curvature & hand dress it or do I need to take out a mortgage, send it out & have it reworked?
Any input is most appreciated.
