I mounted a holosun 510c on.my mcarbo mount.
Sighted the sub2k at 60 yards. Drilling the bullseye. Cloverleading shots.
Went out to 100 yards and it was shooting left like 6 inches.
Back to 50 dead on.
Dailed red dot off center and elevation.
Resighted at 50 and the same thing kept happening.
If I brought the impact to the right I waa drilling it at 100 but then I went back to 50
I was shooting to far right.
I can compensate to get good hits at 100 but this seems odd.
Shooting both eyes open. I have been shooting for 30 years so I understand trigger pull etc. I dont have this issue with other rifles.
