I have a new Ruger American 22-250 (standard length). I have scoped it with a Burris 3.5x10 50mm.
It is consistent in its grouping, but that is not good. I have tried three factory loads: Winchester 45 gr, Federal Fusion 55 gr, and Nosler 64 gr solid base.
Here is the pattern: I have shooting three shot groups with about 1 minute between shots. In all cases, the first two shots are about .75 inches apart. The third shot will be about 2 inches low and about 2.5 to three inches to the left.
I am speculating that it is a barrel heat issue. In checking the barrel float with a dollar bill, the barrel is floated almost all the way back to the receiver, but does begin to bind on the right side of the barrel about 2 inches in front of the scope bell.
Any ideas about how I can correct the stringing?
