I have a mossberg 500 and when shooting it the other day my scope moved towards me about 1 inch.i had the rings tight.i shot about 5 times before i noticed.is there anything i can do to keep my scope from moving or should i tighten after every 2-3 shots?lastly doi tighten my rigngs as tight as i can by hand?

Did you get the shotgun as a combo or just the slug gun and put the scope on yourself?

I would absolutely take off the scope and the mounts, lock tight all of the screws, put it back together, and re-zero it in. I've done this with all of my scopes. They should never move, and you shouldn't have to constantly retighten the screws. If there's the slightest scope movement at all, you will never shoot accurately consistantly.

Not trying to insult your intiligence but are they the right size rings for the diameter of the scope? Even hand tightened screws shouldnt have 1 inch of scope movement just from the recoil of the shotgun. But like pigiron stated you should always put locktight on all of your screws.

Yes pigiron is absolutely right ....take the rings back off and locktite the screws in.i used blue locktite on mine and never had any problems with mine.

im using leupold rifleman 1 inch rings with a 2-7 -32 nikon prostaff scope.i guess i just need to get some loctite.thanks for the help everyone.
