I needed a base for an XR-100 in .204Ruger in a pinch...Make that, "I was desperate to shoot the rifle after waiting 2 years for it and didn't realize a Rem SA base wouldn't fit"
So I cut it short, cold blued it and put a countersunk hole in it. It was supposed to be a tempoary fix, but it's still on it and works fine.
The rifle shoots into 1" @ 300 yards at the moment and I've only done a little load development.
While using the ladder method for load development I got some groups well under an inch at 300...
