Mbgman20
A buddy of mine from work asked me to dig around the internet to find if anybody else is haveing the same problem he is...he said that he has tred all defferent types of ammo and even his own reloads and he cant get it to shoot. He said that at 100 yards it is holding a 3 inch group..any ideas/sugestions.

Thanks

    I had one with same problem , send it back to Ruger and tell them , they will stand by it. Mine was a new gun though is your buddy's new or used. If its used maybe there is no rifling left.

    I'd check the following 3 items: Scope, make sure you have a good scope solidly mounted and that the scope is a proven shooter.
    Stock screws and or bedding, make sure all screws are snug and that there is nothing wrong with the way it's bedded, make sure the bolt handle is contacting metal instead of resting on the stock.
    Clean the gun better than it's ever been cleaned before.
    Do all these things and then shoot it. Odds are this will solve the problem. If not trade that thing off.

    There is an article in one of the more popular gun magazines about Ruger releasing faulty barrels. The one they tested had a pit in the barrel near the muzzle that was tearing of hunks of bullets as they passed through. It was a 204 ruger bolt action that would perform worse and worse after each shot. They contacted ruger and had the barrel replaced.

    I would go along with both MFI and Cyclonus on this one. it looks like you have done all the normal stuff to see if it is the ammo or the shooter. My 2 cents [8D]

    M77's have had a reputation for spotty accuracy for a while. It used to be (from what I understand) from outsourced barrels. They rectified that situation a few years back (would need an expert for exact time) and have gone back to, again what I read somewhere, hammer forging their own barrels, or having it done by a better supplier,.blah blah blah. I have one that has fallen into that new barrel era (~7yrs old) and the dang thing SHOOTS!!

    These rifles are sensitive to the amount of torque placed on the action screws as well. Do a search for the CORRECT way to torque the M77 in it's stock. I beleive the middle action screw (You will want to verify which screw of the 3) needs to be only "slightly" tight!! Just barely turned enough to hold it in. If it is torqued, it will cause a "bridge pressure"[?] across the action and throw off the harmonics/ridgidity. That was what I recall from the article/thread I read a few years back. I purchased a Boyds laminate stock for mine before I ever shot it, but followed the instructions I had read, and low and behold, this rifle has been VERY accurate since the first box of ammo. Mine is a MK II S/S 30-06. My point being that you may try that before giving up hope.

    Next would be to try a "contact point" under the barrel to determine if that affected accuracy.

    don't give up on it just yet, mine sure suprised the heck outta me.[^]

    why chase the game when the bullet can get em from here?....

    Let me know if you can't find the info for correct torque proceedures. I have a few web sites you can search and you will find a thread on it. I can't say that my rifle wasn't accurate before,..but I followed the torque directions on the new stock (no bedding) and the rifle has been a dream ever since.

    125gr NBT with 55gr N140 1/2moa[:D]
    150gr NBT fed prem ammo, 1/2moa[:0]
    165gr SST next on the load list[;)]
    150gr accubond next on the load list[;)]

    Also, I spent a good bit of time running a proper break-in regimen on my barrel (cause the rifle was new). I know my SS barrel has smoothed out soooooo juch, that fouling takes quite a few rounds before any copper is visable at all.
