Question RugerM77 7mm Mag Accuracy

Gentlemen, I have a problem with my M77 7mm Mag when it comes to accuracy. Things I have done: sent back to Ruger twice. 1st they re-crowned the barrel, did nothing for the accuracy. 2nd, they replaced the barrel and stock, little better but not good enough for me to grab that gun from the safe as my number one pick when off to hunting. I have floated the barrel and changed scopes, now has a Leupold VX III 3.5 X 10 X 50mm. I have used factory loaded ammo and I have used ammo I have loaded, still at 100 yards it will not shoot a group I would be confident with on a hunting trip (not even a 4 inch group). I personally feel that the wall of the barrel is to thin to handle the heat and pressure of the 7mm Mag bullet. I love the action and the feel of the rifle, but does not shoot as good as my Rem 700 in .280, or my TC Venture in 30-06. Help!!!!! I am at the point of selling.

I've had a Ruger 77 in 7 mag for about 8 years or so. It's far from the most accurate rifle I have. I can get about 2''groups at 100 yards. Accurate enough for hunting.I've only shot factory ammo. The Federal premium ( I forget what bullet it had) was terrible. I now shoot the Winchester Supreme 150gr Silver Ballistic tips. I was getting about the same accuracy with 150 gr CoreLokts.You do have to let the barrel cool down between shots. I agree I think the barrel walls could be a little heavier then what they are.

RugerM77 7mm Mag Accuracy

Thank you. I am sure there is a wealth of information passed along. Oh, by the way, I forgot to state in my message but I also had the trigger adjusted to 2.5 pounds trigger pull.

You're welcome.

If anything the 2.5 pound trigger pull should help you. Mine is between 3 -3.5lbs.

If you've tried several different ammo types, and can only get close to 4 MOA, it's time for a trip back to Ruger. Their "guarantee" basically says if the gun won't shoot to a usable accuracy for that caliber, give them a call.

Write down the ammos you've tried and the groups you get. It sounds to me like there's still something wrong.

I would contact Ruger again and press the issue. I believe they will make it right, or send you a new rifle.

One other idea. Have you THOROUGHLY cleaned the bore? I bought a Ruger M77 in .243caliber one time and it would not keep the rounds in the scoring rings at 100 yards. Then I gave the bore a thorough cleaning. After that, it shot dime-size groups.

Ruger accuracy problem

I thank all of you for your comments. Just to let you know, yes I have cleaned the barrel with cleaner to remove brass particles left by the bullets, and I have re-contacted Ruger regarding the problem. If Ruger can not satisfy the problem, my next move will be to sell the rifle, hate to burden another with the problem, or to have a gunsmith to install a new heavier weight barrel. I have never had anything but problems with this rifle. Have owned it since 1994. May be time to eliminate it from my collection. Again, thanks for the comments.

I think you have one with a bad barrel.

If the rifle was rebarreled and restocked by Ruger then I doubt a heavier barrel will help. You might try rounding up a couple of friends and promise them a brew if they will each shoot a 5 shot group using the same ammo from the bench. Compare the group size - everyone sights different on a target. If they all average the same spread I would suspect the scope mounts or rings. The rings may be off enough to be slightly bending the scope tube or the mounts may be defective in some way. The rings may need nothing more than a good lap job to allow the scope lay correctly.

M77 Ruger Accuracy problems

I have taken all your comments at heart. Contacted Ruger customer service, rifle is on it's way to Newport, NH. I did check the scope rings, did not see anything that would indicate a problem. Scope mounts/rings were Leupold, made to fit into the slots on top of the rifle, everything was tight. Thanks. I am waiting to see what Ruger has to say.

Ruger M77 Accuracy

Just a update. I received a call from Ruger, who checked my rifle and said that the barrel was burnt out! And, it would cost me $327.50 for them to replace the barrel. I told the customer service person there was no way that barrel should be burnt out, there has not been more than 200 rounds shot through the barrel. Matter of fact, I would bet a months wages that the original barrel and the one they replaced had no more than 400 rounds shot together. Would you think Ruger has a quality issue when it comes to their barrels? I do. They agreed to replace the barrel for free (no charge to me). However, I have had enough, once the rifle returns it will be on the market. I have found that Ruger's customer service is top class, their product not as equal.

Wow - burned out indeed! That must have been a shock. It would be interesting to know if they cleaned the barrel before inspection.
