M77 MII trigger

[DLEB]

Shot a brand new 7mm at the range for a friend awhile back and the trigger was extremely stiff. Since then I have traded for the same gun and the trigger does not feel anywhere near as stiff as it was. It has only had about 10 rounds fired thru it and a few dry fires. Is it me, or is it possible that the trigger lightened up on its own after some use?

A trigger can break in and smooth out over time as the parts wear on them selves and smooth out, with a ruger I won't even fire one with out replacing the trigger... I like rifle basix....the reason that I change out the trigger is because in general a stiff trigger will affect your groups, with a 7mm at a dollar or more a shot unless you reload you want to be looking for that good factory load and not worring about why your rifle won't group...

There is no way I would throw money away on a trigger without firing it first.
Ruger triggers are easy to get an acceptable pull weight out of.

For $25 the gunsmith got my factory crisp at 3-lbs. They do have creep and hard, but take it to a smith.

Like the others said, the 77 MK-II triggers can be re-worked into fantastic pulls.

It's most likely that the gun you're talking about had a small burr on the trigger assembly, and it smoothed itself out with just a few firings.

I think I will try working the trigger myself. From what I read in the article, that Hairtrigger provided, is work the top of the trigger to 90 degs with about .025" engaging the sear. I have an ark stone,  a diamond stone and will finish with emery cloth. A little at a time. Have not worked on a trigger like this before  but have installed new triggers. Oh well, even if I mess it up, there is always Timney and Rifle Basix...Input?

Tried the centerfirecentral site but did not see images/trigger?? Would be good to have some diagram, no instruction booklet with rifle.

try this one, with a link to a "drawing" (don't bother with the picture in my opinion, which is also linked............)

www.centerfirecentral.com/77trigger.html      put the 'arrow' or cursor in the middle of the drawing to zoom in and read the verbage on the drawing itself.     

the "drawing" link makes the articles verbage more understandable.   this is the site i used to work up three triggers on Model 77 Mk II's.     Excellent results with that site.

Thanks ss, I sure appreciate it.  I'll probably work on the trigger tomorrow. I'll post comments then. Thanks again.

Just finished the trigger job on the Ruger. Went from 5 1/4# to 3 1/2#, nice and very easy with the link provided. This is the first trigger I have modified. Have installed aftermarket before. Thanks ss and everyone else, I sure appreciate the help....

Range report...
Trigger job complete and free floated.
8 shot group description.......
Shot 1 - 1" right of center
Shots 2 thru 6 - 2" left of center but in a 1 1/4" group (shots 2 thru 5 in a 7/8" cluster)
Shot 7 and 8 - 3/8" apart and forms 1 1/4" group with shot 1.
Looks like scope to me...
Trigger job and free float did its job..Now for a scope fix......
What do ya'll think?

evidently you know how to work with a diagram and some explanation off a web site.   congratulations on the trigger job.   

you said that you free-floated the barrel.   it sounds like you did that without firing a group first....after having done the trigger job.   

i'd recommend you try shimming the barrel so that it is once again pressure bedded just behind the tip of the forend.   then see how it shoots with some variance in the thickness of shimming and upward pressure on the barrel.     i would recommend that a shooter never free-float a sporter-weight barrel before shooting it.    it is widely-reported that free-floating a barrel is a great idea.   but that's only if other tricks done beforehand don't yield Good Results.    ......at least that's my opinion.    (i don't see Remington pressure bedding so many Model 700's ..... with their excellent accuracy in so many cases ..... as an accident.    it is a cheap way to help accuracy in many rifles).   

let us know, please, how it goes,

Sorry ss, I did shoot before doing any mods. Groups were about 2" or so. Looks like the free float definetly helped, but I still have a scope issue.  But not for long. Yea, I agree, I don't like to do anything unless I shoot a new rifle first to see how it is going to act.

congrats on your good work!

While free floating can often help, as it seems to have done with this one, some folks would argue for a bedding job as well.  Haven't bedded any of mine yet, although the day may come.  Sounds like you have a good shooter and I suspect a little load development will cause it to do even bettter.

Put a Simmons Whitetail Classic 6.5 x 20 x 50 on last night. On sale at Midway. Couldn't pass up the price........
We'll see if it works out at the range..................
