I just acquired a new-to-me 336. A previous owner had decided that the spot where the bullseye was would be an excellent place to put a sling swivel stud. I removed the stud, installed a new bullseye, put tape around it, and sanded it to the contour of the stock. The problem is, though, that the hole that was drilled to countersink the swivel stud is slightly larger than the bullseye. I looks nice from a few feet away, but not so much up close. Any suggestions on how to fix it?
