Friend bought one on my recommendation and we are having issues getting it to group. We get significant vertical fliers. Shoot 4 shots, 3 in 1.5-2" and one flier 3.5-4" higher, or sometimes even lower. We are bagging the gun back on stock to avoid the sling stud and using several different 140 grain loads. Trigger is good and scope is mounted well.
I can slip a piece of paper between barrel and stock...not only behind pressure pad in the forend, but actually at the pad with a little effort. It is tighter, but still fits. That seems very wrong to me. I would think you would want free-floated...or...good solid contact at the pressure pad. I am guessing that slight contact at the pad is causing the fliers by the barrel adjusting its contact location between shots and at different temperatures. Barrel is very thin contour. We are wating 4-5 minutes between shots and it was very cold on the day we shot last.
I expect to try shimming at the pad with a business card to increase pressure somewhat and see what happens. Alternatively, we might try free floating down the roda, but the shimming plan is less permanent and worth a try.
Note I do not believe our technique is the problem. I can shoot 1.5" groups at 200 yards with some of my handguns and my rifle technique is not that bad. I shot sub 1/5" group with a pistol at 50 yards off of the same rest that day. Solid concrete bench.
Any thoughts or suggestions are appreciated.
