help with accuracy before I throw away this 30.06
I posted a topic several months ago about my ruger m77 30.06 with leupold scope and the terrible accuracy i was getting. I took it to a gun smith and he checked all the various possibilities, i.e. scope tightened, screws not over tightened on gun, and we decided to free float the barrel. I shot is today and i'm getting 5 inch groups at 50 yards with severe horizontal stringing. Vertically i'm fine, but from left to right i have a 5 inch spread!!! I've tried all different bullet weights and companies, so I think its something else. What hould i try next. I'm about ready to get rid of this gun because its really peeing me off. I have other guns i shoot fine, so its not me. please help!!!!!!

If it were a simmons scope I would tell you that the horizontal crosshair were loose... leupold??? Call factory and ask questions 0 -
Ya know, I dont know if you have check it or not but I have seen 2
M77 with way to much free bore hope that helps.0 -
Have you considered sending it back to Ruger for a factory check-up? They know best how their products should perform & have the tools & people to discover whether your M77 has suffered somehow since it left their works. 5 inch spread at 50 yards is pretty extreme for any decent rifle; if there's little vertical variation my suspicions would be that the scope and/or mount is at fault. 0 -
First thing you do is switch out the scope with another. You will then find out where your problem is. 0 -
Rings? Maybe you need shims? Loose base?
Does it have sights? If so, try open sights and check for accuracy at 50yds. If you have the same prob, you know it's not the optics.
Next step would be to check the action screws and barrel to stock screw if it has one.
No offense, but the problem might be between the gun and the chair (you), have someone else take two different 3 shot groups and compare results.0 -
Give it to me, that will fix your problem.

I dont think its the shooter as he already stated he doesnt have this problem with his other guns. I suggest you take the scope off of it. If you dont have open sights thats ok. Fashion out of a piece of paper a front sight post, by taking a strip of paper approximately a 1/2" wide and the length of a business card or credit card, in fact a business card would be great for this. Fold the strip in half, with the crease of the fold up and the open end down, take each of the open ends and fold them back out and up to touch the crease, so that you have made a (W), now fold the pieces you folded up to make the (W) back down so that your piece of paper makes looks like an upside down Capital (T), invert that T which I just put in parentheses and you will see what I mean. Now the original crease you made on the very first fold when you folded the paper in half is going to be your front sight post, and your little flaps at the bottom of the inverted (T) are going to be taped to the barrel to anchor the front sight post. Take a marker and color a bit of the paper post so that you hold the same amount of front sight above the receiver each time you shoot. You dont need a rear sight for this, just put your cheek on the stock where you always do, center the front sight over the receiver and hold that little bit of colored front sight up enough so that is all you can see of the front sight and fire. Try this within 25 yds. to make sure you are somewhere close to hitting paper, adjust the front sight if needed, to get you more to the center of the paper. As long as you are hitting somewhere on a paper target it isnt important where you are hitting. Now move it back to the 50 yds. you were shooting with the scope on it. Fire for group, dont worry about where it hits, so long as it hits the paper. If you tape the sight on good, you will be just fine, I've done this before. If your problem is no longer apparent with the paper sight, its the scope. I can group my shots in 1.5" with a muzzle loader at 25 yds. this way, so you should be able to get 2.5" with a good shooting rifle at 50 yds. allowing for the lack of a rear sight. It will be worth your time to try this and prove once and for all if its the scope or not, then you take your problem from there.

Wad up some business cards and jam them under the front of the barrel, only for the first half inch or so. If some hangs out, who cares. Then make sure you have jammed enough under there to keep the barrel tight, (you have created a contact point at the front of the stock) Sporter weight barrels often need a contact point at the front to shoot well. Floating is mostly for a bull barrel which controls balistic harmonics by the "tonnage" of steel surrounding the bore. try that and see if the groups come together. I have found that the majority of times, a horizontal string is stock related.
A great rifle with a junk scope,....is junk.0 -
Find out where 'GUNNY' Roberts stationed and take it to him...When he has it shooting good enough for Him...! Go pick it up and slip Him a couple of Bucks and a Steak Dinner....Or do as Clark says...ship it to Ruger and let them evaluate the situation....

5 inches at 50 yards can't hardly be the rifle. I think your problem is the scope, even Leupolds can break. Slap another scope on it and try again or try Robsguns suggestion. Even with poor substitute fixed sights you should do better than 5 inches.
The hint would be the vertical stringing, loose action screws, scope mounts etc. would more than likely give you two distinct groups as the rifle bounces from one place to another and back again.

oops my bad, horizontal stringing? Does it look like two distinct groupings? If so you may have something loose.

I believe the first step is to eliminate all the components of the rifle. Lock the rifle in a rest and fire a three shot string. If the group is open in this case, then the problem is with the rifle.
If not, then it is the scope or the mount.0 -
I had a Ruger 77 in 270 once that did about as good. Traded it in on a Rem 700. Problem sloved. 0 -
I'm going to try the business cards first, then switch out the scope and see what happens. I'm keep you all posted.
Thanks for the help!!!!0
