m77 ruger 7mm

I have had my m77 ruger 7mm for 12 years all of the sudden having trouble getting it zeroed anyone having this problem with this rifle?

There's probly half a dozen reasons. I know someone else with one of these rifles that's fairly old and the thing is still a tack driver. so ammo change could be a possibility. check your rings and bases to see if they are tight. check the stock make sure its properly tight and not swollen or cracked anywhere. final thing I would check would be the scope, optics sometimes get hit just right or wear out and wont hold zero anymore.

 I have a couple of them and one has been my go to rifle for 30 years without a fail. I'm with the majority, betting it's a scope or mount issue.

Have you re torqued the action screws? Some of the rugers I've dealt with need to have the front angled action screw tightened first and as absolutely tight as you can get it then snug the rear and just tighten the middle enough it wont spin out. I also locktite these after every time I place the action back in the stock.

I have a M77 and it will do exactly what you are describing when it gets dirty. Clean the living daylights out of it and I will bet it starts shooting great again
