    My Ruger m77 (the oldie with the tang safety) is great in every respect, but I was in a tinkering mood and tried to see if I could adjust the trigger pull weight. There is almost NO overtravel, No creep, and it breaks clean at 4.5 lbs every time. I was hoping there was a way to bring that 4.5 down to a 3-3.5 pull. I don't think I need to mess with the overtravel or creep.

    After some research online, I found what I thought was the correct pull weight screw (part D-43, according to the Ruger expanded view), but the darn thing was so small, I couldn't even tell what head it had on it! It looks like a rediculously small Allen Wrench, but I didn't have one that fit it (the smallest I had was a 1/16). I found how to tweek a model 70, Rem. 700, and a Ruger m77 mark 2, but NOT my m77!

    What size/head type is the screw?

    Can it be adjusted at all?

    Any info you can provide would be great. Thanks HighRoad!

    I have no idea if you can do what you want on a Ruger, but that sounds pretty good already.

    I agree that it's already a very nice rifle with a trigger that will easily drop game, but I want something that breaks a little lighter, and I'd like to know HOW to achieve this.

    I know I said it broke at 4.5 lbs, but after further investigation (and a better test scale), it's more like 5 lbs.

    Again, I'm wanting to adjust the pull weight. What is the easiest way to do this, and what tools do I need to accomplish the task.

    adjustment

    WCA: I have never done it myself, so take it for what it is worth, but is is my understanding that you can adjust the pull on the original 77 without taking it apart. Turn the rifle upside down and look at where the trigger comes out of the rifle. There should be a small hex screw. You turn it one way for more pull the other way for less. I cant remember which but you should be able to find it on the net. Good luck!
