Trigger ADJ on 77 Rifles??

[chuck]

I have 2 Tang safety 77 one is a 35 Whelen that I had to put a Timney trigger in the other is 338 Win Mag that the trigger was OK from the factory, I am thinking of buying another 77 tang safety and I would like to know if and how a person could adj the original triggers? I know they have 2 screws in the bottom of the triggers but they don't seem to do anything. I have the one I took out and replaced with a Timney I can experiment on, Timney triggers are Great but Expencive.

WOW! My post is the #3 post about Ruger Rifle Trigger adj, and no ans must be no one has ever done one
So when I get around to it and IF I find out how to do them I'll post it here for others.

The tang safety Ruger triggers are adjustable, but only to a very limited extent. Whenever I wanted a really nice trigger on one, I went aftermarket (Timney).

The 77's are like m70 winchester. You take trigger apart and use a centerless grinder to remove .00010 of sear engagement surface, and then trigger pull can be adjusted with spring tension. Only a limited amount, but you usually get 3 1/2 to 4# trigger pull. That's just right for a hunting rifle. Any less in not safe. Hope this helps. Bhk

I would love to see you do it. How about a short video demonstrating how to remove one ten thousandth of an inch from a flat surface with a machine designed for grinding round workpieces. In case you really meant a "surface grinder", please explain how to remove a tenth with repeatable precision.

There is no need to modify the trigger. It is fully adjustable. The sear engagement screw even has a notched head to give a detent effect when it is turned. Each notch is equivalent to about .002" of engagement. .010" should be the minimum setting for safety with .015" a better choice.

It is essential that you understand the trigger geometry before you try to adjust it. BTW it is nothing like a Model 70 trigger. It is basically the standard override style used in most bolt action rifles. Timney has made many thousands of them for all kinds of rifles for at least 60 years.

The above comments are directed towards the early Mod 77 tang safety rifles thru about 1985. Later rifle's triggers might be not be so readily adjustable. I have no experience with them.

The 77 factory triggers are adjustable to a small degree. Just go with a Timney. Send the rifle to Timney and they'll fit one for you for a price. I changed one on my old 77, but my old model 70, 270 win is my right arm when hunting.

WOB Thanks fer the Info, I have a spare one I took out of one of my Rugers I got it out and saw the screw you are talking about the one I have was screwed all the way in turned the screw out and felt the clicks, so I now know what you are talking about, I just bought another tang safety one in 7 mag with a so-so trigger so will take it out of the stock and do some adjustments and will let you know how it works but it will be a while before I get to it thanks again for the Info.

I agree with Black Hawk Kid. I have done a bit with my 77/22's. It called for a very light honing procedure. My plan was if I did to much to just put in an aftermarket trigger. It turned out fine.

There are instructions on the net, not as simple as the average Model 70 or 700 job.
