Good front rest? how about rear bag? Are you holding consistently each shot? How is your reloading technique?
If all else fails, return it to Leupold for a free check up.
It still shoots the same at around 1moa with the 3.5-10 back on. I've checked the mounts and are all secure. Testing has been done at 100yds so far, off a Sinclair front rest and bunny ear rear bag. Reloads have been tried from two diffferent relaoders, bith using redding match dies and match components. Lots of time spent on prep, so hopefully not the problem. It achieved 1/2 MOA with these loads and the 6.5-20 scope.
I think that it may be the shot follow through..... The gun is quite lively to shoot off the bench probably due to it being quite light (7.5 lbs all up) I think if it weighted 10lbs it would be a lot easier to shoot good groups. Trouble is, here in NZ we walk a long way and climb som damn big hills so that's not really an option at the moment.
