M77 concerns

Watch for the trigger guard. It's made of aluminum and it can crack if you tighten the front screw too much.

I have owned hundreds of Ruger rifles and I torque the living crap out of the front angled action screw, it is one of the keys to good accuracy with an M77... Ruger recommends hyper torquing the front screw, it is the reason that they have switched from flat head screws to Torx screws.

Interesting.....

How much torque are we talking about?
 
My first .300 Win Mag rifle was a Ruger 77 tangsafety model with 24" barrel. Great rifle & very accurate. Only sold when I switched to a Browning Abolt with the 26" barrel.

I've had good luck with Ruger rifles. My next tangsafety M77 was in 7x57mm. Still have it. It will do 3 shot cloverleaf at 100, if I do my part.

My first spankin' new one was a Model 77 MkII in 6.5x55mm from Lever Arms in Vancouver, B.C. circa 1992. Some lucky bugger from the EE has it now, as it went after a Remington Model 700 classic in 6.5x55mm came my way.

Anyway, my advice is, see if you can shoot it. You might be very pleased.. ;)

Front angled one, yes torque it to hell. The rear one torque it hard too. It's the one in the middle you have to be gentle with.
 
The way the Ruger is set up, from the factory, the sole purpose of the center screw is to keep the front of the trigger guard and the rear of the magazine box in place. There are three ways to prevent breakage:
1. Don't tighten the screw. Use some blue Loctite on the threads and set the screw so that the guard just touches the mag box.
2. Use a sleeve over the screw to prevent bending of the front of the guard.
3. Install a pillar at that location. A pillar is just like a sleeve only it is attached (glued) to the stock.
It is also possible to replace the aluminum guard with a new, steel one.

The proper process with all bolts removed, is to install the two trigger guard screws just snug, then install the Mag plate with angled screw and tighten the bejeesus outta it... then tighten down the rear trigger guard screw with firm, moderate pressure, then re-snug the front trigger guard screw with "light" pressure... as said above, a dab of blue loc-tite on the front TG screw wouldn't hurt. I have never found the need to use a torque wrench to achieve return to POI or consistent accuracy.

Note; The torque on the TG screws can affect how much engagement is on the Mag plate latch, so if there are problems either latching or unlatching the Mag plate, play with the torque on the TG screws.
 
Accuracy can be hit or miss on newer Ruger 77's as well.

I've had a couple of Hawkeye's that wouldn't shoot worth a damn!

After countless trips to the range with several different loads, I gave up.

As much as I like the look and feel of them, I won't be wasting any more time and money on Ruger 77's.
