Default Ruger M77 shooting groups

Not real happy with how my Ruger is shooting. 1.5" groups at 100 yds. Yea it'll kill a deer, but no telling what it's shooting like at 200,300....

Took stock off last night and seen where barrel is touching stock out toward the end. From what I've read, Ruger did this in purpose, creating a pressure point lifting end of barrel.... decided to take my chances and float barrel, got it sealed up last night and I'll shoot it this afternoon and see if I made it better or worse.

Next step is lightning trigger pull, I know this will help, supposedly pretty easy to get to the 3ish pound mark by replacing spring and doing some polishing.

If these 2 things don't satisfy me, I'll make an attempt of glass bedding action and recoil lug.

And last, if all this fails, I'll send it back to Ruger and see what they can do with it.

Hers a pic of where barrel was touching stock

Has anyone done any mods to their wood stocked M77 to make it shoot better?

Quite a few manufacturers use a pressure tab on their stocks. More times than not the gun shoots better with it removed.

DD, a simple way to float the barrel is to shim the recoil lug. You can also wrap a dowel with sandpaper to remove enough wood to float the barrel. I've done both with my M77. Also sent the gun off and had the trigger worked on. Breaks at 2 3/4#.

Inch and a half groups ain't bad for a hunting rifle. I figure you've already tried different brands of ammo to see which one your rifle "likes". If none of these fixes don't satisfy you, it's new barrel time.

BTW, if you sand the stock, be sure to paint/seal your work zone when finished. This will avoid the possibility of moisture entering the wood and causing the stock to swell.

That's what I did, (dowel with sandpaper). I applied a coat of poly to it after i sanded it to seal it .

I've tried 3 different brands of factory ammo, none seem better than the other.

I'm not gonna go through re-barreling , no sentimental value here, I'll sell it and find something else before I do that . It's not terrible the way it is, I just would like for it to be better.

My reloads are better but for a factory load my M77 does really well with Hornady Superformance.

I'm sure Ruger did it on purpose, but what a sloppy job...in the photo it doesn't even look centered. I can see why nothing shot less than 1.5". I've not see anything that shot better with pressure on the forend. My dad when he was building rifles used to bed the area where yours was rubbing. The work looked great, they still didn't shoot as good as they would floated.

Get the accuglass kit from Midway USA...pretty easy to do.

What year Ruger is it? 10 to 15 years ago Ruger had a bad rep of not shooting well. I had a 25-06 with a heavy varmint barrel...didn't come close to being impressive at the range. I got rid it...

I've read about the tightening sequence, haven't tried shooting since I've floated barrel, waiting for trigger spring to arrive, hopefully this weekend I'll see what she does.
