Rugar 77 tang safety 220 Swift.

Im having a problem with the trigger on this rifle. I bought it used a while back shot three boxes of factory loads thru it fine. On the fourth box the trigger ?like locked up, felt hard and the fireing pin never moved. Recocked it once to no avail. Second recock it fired. Fired for six rounds and did it again. Recocked ita half dozen times then and nothing. Still acts like some thing is locked up.

Anybody able to advise me on a simple fix?

I'll take a shot at this until someone that knows better comes along.  First step of course is empty gun, then clean it well.  We all know this, I just like saying it.   


Ive had a similar experience with cocking/trigger pull (but different firearm) when the firearms trigger overtravel screw was out of adjustment.  In fact there is a flyer out from ruger providing notice of this problem and describing as one possible scenario the results your are having.  I tried to attach but not sure it worked so I pasted the Notice below.

Notice to Owners of Ruger
M-77 Bolt Action Rifles
The trigger overtravel adjustment set
screw (shown on right) in a few of these
rifles may not be securely tightened and
may move too readily. This change in
original adjustment can, in extre m e
cases, either cause the rifle to fire unexpectedly
(with the safety “off) or cause
the rifle to not fire at all. This may occur
suddenly, without warning.
Current production rifles have this
set screw permanently secured. These
rifles have a “T” inscribed on the underside
of the bolt handle. This condition cannot occur in any of our other
firearms, such as the 77/22, 10/22, No. 1, No. 3, or the .44 Carbine, as their
trigger mechanisms differ.
For your safety, we ask that all owners of M-77 rifles (except those with a
“T” underneath the bolt handle) contact us, using the coupon below.
You will receive a new locking screw that will replace your present overtravel
adjustment set screw and detailed instructions for quick, easy installation.
There is no charge for this service and replacing the screw will have
no adverse effect on trigger pull.
Do not use your M-77 rifle until you have received and installed the
replacement screw.

Hey Thank you very much for this reply.



The picture I found on the net doesn't show any screws.


Now to go look for that T.

Thank you again

Mine has that T on the under side of the bolt.

Again thank you.

It sounds to me like the sear may not be staying on the trigger when the gun is cocked. Take the action out of the stock and cycle the bolt while watching the trigger. You should be able to see it reset itself into the fire position when you open the bolt. If the trigger falls or disengages when you close the bolt it's a simple problem to fix.

On the trigger itself, near the top is an adjustment screw. You can get to it thru the rear side of where the magazine well is. There is a set screw in the hole that keeps the adjustment screw itself from moving. Remove the set screw and turn the adjustment screw in about a half turn. Cycle the bolt and try the trigger.

Hope this helps you some, mine did the same thing. Very frustrating to say the least.

Roy D beat me to it. I have seen it about a dozen times. Alleyyooper-- those pics are the MK II trigger system. The originals (with tang saftey) had adjustable triggers

Thank you on the update.
