Leupold Bases Drifting?

I took the new 700 7mmRUM to the range for the first time yesterday. It already had a one piece Leupold style bases on it so I bought some matchings rings for it. I centered the scope for windage (it came off another rifle) then used the rear base to adjust windage during the bore sitting.

After about 10 rounds I am still at the same point on impact...so I move the scope again! I have the gun on a bipod and sand bagged well...set the scope back on bull and move the cross hairs to the bullet hole. It would be about half way to where I wanted it on the next shot and back to the original spot after another shot!!!

Somewhere around the 15th to 18th shot I run out of scope adjustment! Thats when I noticed the rear ring was not longer centered on the rear of the mount. I forgot my screw driver and bent a penny trying to get the windage screws loose. I tend to overtighten...any way I recenter the mount and my windage is WAY off...recenter the scope and start over. It stayed this time, but I am very worried about the mount doing that again.

I don't normally buy this kind of mount...does this happen often?

BTW-it shot less than 3/4" groups after that with Remington factory ammo.

OMT-Limbsaver recoil pad was money well spent too!

Could it be the scope that's causing the problem?

No, after I took the ring loose at the base and got the scope centered on the baseagain, then centered the scopes windage. It was dead on when I bore sighted it...it was only 6" left of the bull. I did the same thing as I did before...bipod and sand bagged the gun...cross hairs on bull...adjust cross hairs to bullet hole...next five were in a small 3/4" group.

What I thought was strange...the scope (ring on base really) was left, but the right base screw was very tight. Like I stated earlier...I bent a penny trying to loosen it.

I don't know..it acted very odd and plan to junk the bases after the season unless it does it again.

OMT-the scope shot some one hole groups two months ago in my 7mm RM and it went from the range to the safe. So I fell pretty good about the scope.

Thanks
