Scope adjustment question

[duckloads]

I put a burris scope on my XVR using Burris mount and Leuppold rings. My scope base has dovetail mount in the front. It is the type where you insert the ring and turn 90 degrees to lock it down.

The rear ring is held down with two screws, one on either SIDE of the mount. I was told very course lateral adjustments can be made by loosening one screw and tightening the other.

This is supposed to save the scope's internal adjustments. I'm shooting 2" to the left at 25yds. What direction do I move the rear of the scope using the mount screws?


Thanks

You move the rear of the scope to the right, Turn the right screw out and the left screw in. You'll find the rear ring will deform in the screw head notches and the bottom surface that contacts the base will need to be filed flat. On a gun with considerable recoil you'll probably end up wanting a dual dovetailed base.

Thanks Tom'

According to Burris website, that was the only base for the X frame. You a probably right. Locking down that front dovetail was comforting.

The burris base I bought has a small socket head (hex key) cap screw installed just ahead of the back adjustable ring. What the turd is that screw for?

The socket head is literally a bumper for the rear ring to try and keep it from moving forward under recoil. The X frame uses the same mount as the K, L, N frame. Leupold makes a dual dovetail mount but you'd need to check and see if it mounts down into the rear sight cut-out like the Burris rather than laying across the top of the frame like a turd which many do (are). I like the Burris base, but keeping the rear ring in place on a gun that recoils can be problematic.

FYI, I have the Leupold dual dovetail mount, and it does protrude down into the rear sight cutout. It also has a small ledge in the back protruding down a very small amount to help take up some of the recoil instead of leaving it all on the screws. It attaches with 3 included screws, and I have only shot it about 20 times (240 gr XTP/MAG @ 2050 fps) but so far it hasn't budged. Hopefully it stays that way. That along with medium DD rings and it looks very cleanly mounted as well. I am looking forward to getting some time at a distance (100 yards or more) with a rest to see what it groups. It's this one...

Check out this mount from SSK. The T'SOB. It was designed expressly for hard recoiling guns. I have one on my .475 Linebaugh. While your gun may turn up more energy at the muzzle, it won't recoil any harder. Mine is lighter and has no brake system on it. The T'SOB holds my scope in place!
