missing barrel screw
ok, to make a long, frustrating story short, i had to drill out my rear bottom grub screw for the barrel. now there is about a quarter inch hole where the standard threaded hole used to be. nothing has worked up to this point to fill, tap, re-drill, or otherwise repair the frame to accomodate another screw of any size. how much potential does this have to affect long range accuracy or perhaps a poi shifting problem? i havent been able to shoot long range yet, but i have parts for a .25 conversion on the way, and i fear that the forces of this more powerful setup may make the barrel more prone to moving. again, this is the bottom rear screw. do i have a problem?(or leave it go)

If it stripped out, and your talking about the barrel retaining grub screw, the fix is to dirll and tap it for a 1/4-24. Then you take a 1/4-24 set screw and chuck it up in your drill and turn the bottom half of it down to .18, which is the old diameter of the 10/32 screw. you then have a dual diamater screw hole that is maybe a stronger one than the 10/32 screw was.
I have had to do this on the two side screws on my Condor.
Your problem is that you may have made too big a hole to tap to 1/4-24 by drillling to 1/4 inch.
