Ruger 77/22 Mag misfires?

BowGunHunter
Shooting a Ruger 77/22 All Weather .22 Mag. Just got the gun so I don't know the history.

Spent the morning at the range shooting and had way to many misfires. I would guess almost 40%. I was shooting Winchester .22 mag.

I'm guessing it was the gun and not the ammo. What needs to be done to correct this problem? Will taking apart the bolt and a good cleaning work? or does it sound like an overhaul of the firing mechanism?

Thanks

    Are they all hit the same? Broken firing pin?

    Will they fire on a second hit or on a different spot on the rim [?]

    I didn't try. I just threw them in the misfire bucket.

    I was wondering at the time if I should put them back in and try again...but I didn't. Is it generally ok to do this? or a bad idea?

    I am new here so don't take this as gospel. Many years ago I was given a Mark I Ruger. It had apparently been dry fired many times, and as a result the firing pin had peened a dimple into the chamber at 12 o'clock. Removing the part of the dimple that facilitated easy loading was easy, but the firing pin was shortened by .004, enough that the pin strike is very light by .22 standards. Guess I will have to replace the pin some day. Hope this helps.

    First, attempting to fire rounds a second time won't hurt anything, though it won't help the basic problem either.
    The best advice so far, IMHO, is what you offered yourself.
    Start by stripping the bolt, cleaning it thoroughly of all oil, grease, etc. LIGHTLY oil, reassemble, and see if that takes care of it.
    While you're at it, check to make sure the barrel bolts are tight.
    Haven't encountered it before, but if someone removed the barrel and didn't fully tighten the two v=block bolts, or if there was some crud in the way when they did, that might give you the problem as well.
    Good luck.

    Follow Mr. Crosby's instructions. If it is not the bolt or firing pin, take the barreled action out of the stock, and make sure those two bolts are tight...but don't over torque them, and break the wedge block.
