Hi everyone, I'm new on here and new to rifle shooting in general. Most of my life I've been in shotgun only hunting counties here in va. Anyway. My dad got a browning hells canyon in 300wm with talley one piece mounts and a Swarovski z3 scope. I help install the scope, lapped the rings for a good fit, leveled it all up and tryed it out. We where shooting at 25 yards just to get on paper, tryed to adjust to the center of the target before moving to 100 yards. We ran out of windage on the scope at about 1.5 inches to the left of center. Any ideas what I should look at first ? Thinking bur or something on the bottom of the mounts, top of the chamber area or possibly I didnt get the rings lapped correctly? I have the exact same scope on my Remington 700 7mm rem mag ( different mounts ) mounted it the same way and it works perfectly. Any suggestions would be appreciated.
