    Default Trigger Adjustment

    My Wby info says the trigger pull weight can be adjusted. The screw in the bottom of the action in front of the trigger, I turn in and turn out, I don't feel any difference.

    Any ideas?

    My accumark would only back off to 3#. I removed the spring and removed 1 coil, refaced it and reinstalled it and could get to 1 1/2#. I took it back to 2# and I like it there.

    AQpart from the trigger return spring being way too heavy there is also the sear engagement adjustment. That is the small screw that is just behind the rear receiver ring and it goes at an angle. The bigger screw is what holds the trigger on to the receiver.

    If you screw the sear engagement screw in you reduce the amount of engagement. If you go too far then the gun won't cock or the gun will cock when the bolt is worked slowly but it will fire if you slam the bolt closed.

    With correct sear engagement and lighter trigger return spring Wbys will usually come down to about a pound. Actually when a case is in the chamber they will often allow you to come down to about 10 ounces and that is because the spring loaded ejector acts as a buffer when you rapidly close the bolt.

    The trigger return spring apart from being too heavy is also held captive under tension. In other words even if you took the weight of pull screw out of the gun you will still have quite a heavy trigger pull.

    First, avoid tuning the springs before you try out proper adjustment.
    The "old" instruction manual shows how to adjust the trigger.

    The old manual can you download Here.:

    I had a trigger job done on my Ruger 77 (you know, the attorney trigger at 7 to 8 lbs)... My smith brought it down to 2 and a half lbs with no creep... I've adjusted my Accumark down and it feels very close to that number so it's probably about 3 lbs is my guess... Has a very small amount of creep which is not troublesome at all.... I'm guessing that like many factory triggers they are somewhat different from one to the next... I've got no complaints from mine but I may just have gotten one of the lucky ones... Like that nice tight chamber with factory ammo .....

    Looks just like my old manual. I could only get the trigger down to " THE POLITICALLY CORRECT" 3 1/2 lbs. I did the spring trick and now it's at a perfect (for me) 1 3/4 lbs on all except the Jap model which is at an even 2 lbs. They are wonderfully crisp now. You must be very careful when performing this procedure if your not experienced however. Great care must be taken and though testing must be done to insure it wont go off whith any jaring movement or impact.
