Another option I have used is to drill the body and silver solder a new tip into it. If you do it right, this repair is strong and undetectable. Here is one I did just a couple of weeks ago: http://skytteforum.com/default.aspx?g=posts&t=31872

I agree. The hole is actually rectangular, which indicates that it must be the bottom of the hole showing through. My initial thought was that you can turn a small plug and press it into the hole to make it more shallow. On second thought, this may not be strong enough, a blown primer could possibly blow the plug out.
