First of all, let me say that I'm far from experienced. I only shot ten rounds due to all the cleaning. I need an adjustable cheek piece on this gun. I used a hunting glove on top oF the butt to give me a cheek weld(ish).
I used another glove and my hand to rest the rear of the gun. The front has a Harris bipod on it. I was shooting prone.
Ok, brass tax, the gun shot great. I used the remove the bolt and look through the barrel technique of bore sighting. My first shot was an inch from the X, high and to the left. The next 3 shots were about 2.5 inches high and left, in a small cluster measuring .509 end to end on my digital calipers. I was just using some Winchester "big game" ammo. Is that a .201 group? I was pretty excited about the group, and didn't want to mess it up, so I pulled it down, and used another target. Pretty juvenile, I know.
The next 6 shots measured .877. I'll try to get some pics up tomorrow.
