Home Forums Hunting & Shooting Hunting Optics Problem with Leupold STD bases/rings

I just installed new Leupold STD bases and rings on my buddy's Remington 7600 (30-06). I've used the STD on many rifles through the years and had no issues.

We shot about 7 shots and had the rifle sighted in at 50 yds. The next 2 shots at 100 were off the target. Then noticed the rear ring had slid 1/2 " forward off the rear base. The base windage screws had loosened.

Tightened everything down again. Used a coin (quarter) on the windage screws. Within 3 shots, same thing happened. Snugged everything down..real tight yet again.. and we then checked the windage screws after every shot... and found they were just not holding up under recoil.

I haved used the STD's for 7600's on a .308 and 7-08 and they worked great.

Before I contact Leupold... and I missing something ? Any suggestions ?

Thanks... Rob

With 7600 automatics, unlike bolts, the bolt and and action work jerk back and that may cause problems with STD setups. Try a weaver, talley LW or DD.

7600's are pumps not automatics.

I have 2 Rem 760s (243, 30-06) and have never had a problem with Leupold STD mounts. Just make sure they're tight - using a screwdriver. If they still come loose, send them to Leupold for a new set.

And people wonder why I use dual dovetails.

Thanks for the responses !

I found the problem... the front ring screws weren't tightened down enough. That caused the scope to slip forward from recoil.. it carried the rear ring with it (out of the rear windage base).

I too, prefer DD's, but Leupold doesn't offer them for the 7600.

Thanks... Rob

STD rings are crap. The ring sheared off of the rear mount on one of my M70's. Won't use that junk ever again.
