Ruger M77 Glass Bedding

I have a Ruger M77 30-06 with a laminate stock that I need to glass bed. I've posted about this rifle previously but basically the rifle use to shoot pretty well. To try and increase accuracy even more, I free floated the barrel a couple of years ago. Instead of making the accuracy better, it got much worse. Through experimentation I found that sliding a business card between the forearm and barrel an inch or two from the front end helped immensely. I just ordered a glass bedding kit (Araglas Gel Bedding Kit) and now need to decide where to bed exactly. Should I bed the action (behind (but not below) the recoil lug and under the chamber), the action and barrel (dab of bedding material an inch or so aft of the end on the forestock), or just the barrel? Thanks in advance!
 
Bed just the action, front and rear. I bed the bottom of the recoil lug and then remove a bit of it with a dremel. Some use tape instead. to me, the Dremel is easier and quicker. To each his own. I do not like doing skim bed jobs. I take enough material out of the stock to form a strong bed.
 
I would bed the action first, and then go to a pressure point on the barrel only if the action bed doesn't help.

(I would do the front and rear action areas separately, since the angled front action screw adds complication. ...So it's actually two bedding jobs before you can even test.)
 
Don't M77 come with a pressure point on the front? I have an 80's vintage Ultralight, that, I believe, had a pillar installed from the factory (could also be my 65 year old memory).
 
Neither M77s, nor M77 Mk IIs came with an intended factory pressure point on the barrel.

Some had warped stocks that applied pressure, but it was not engineered into the design.
Pillars, as well, were not original. If you have one, it was a modification/upgrade.
 
I bed my Remington years ago, worked out great . I used devcon , the wait time for curing is the nerve racking time . I found the video's on line very helpfull . Removing the clay was a pain .
 
"...free floated the barrel..." Guarantees nothing and your Ruger clearly dislikes it. yYu can try just putting the pressure point back in first.
"...the action and barrel(dab of bedding material an inch or so aft of the end on the forestock)..." Yep. Around the barrel band screw. Follow the directions on the Acraglas box. The idea is to make the barreled action and stock one piece.
Tape does nothing at all.
 
I just bedded my M77 7mm mag with the tang safety. I installed aluminum pillars that had the angles pre cut for the front. Its a little tricky to get pillars in since the front one is angled. I easily get sub MOA. I also reload and you can do alot by playing with loads. If you use off shelf ammo you will need to experiment with different ammo and weights.

I bedded the action and rear tang. I use some tape on front and side of the recoil lug. I also bed about 1-1.5" infront of lug (up to where the chamber starts to taper). You can always dremel some out if it doesnt work.

Im a fan of free floating the barrel but every gun is different. The one problem i have with pressure points is you need a rock solid stock. If your stock moves at all with temp or humidity you may see seasonal changes as your pressure point pressure changes.

The M77 is very sensitive to torque settings. Check specs for yours. I have pillars in mine and torque front action screw to 95 inlbs. Back screw to 35 inlbs and middle screw just enough to hold trigger guard in place.

Good luck
 
Thanks for the responses. Why bed the front and rear separately? Does it matter which one I do first (front or rear)?

The front screw is angled on the M77 series of rifles. It adds complication to the job - especially if using pillars. ...And I wouldn't bed an M77, M77 Mk II, or M77 Hawkeye, unless I was installing pillars.
It's easier to do the areas separately, unless you hog out some of the stock for clearance.

It doesn't matter where you start.


If a rifle shoots best with a pressure point, something is screwed up. Usually bad bedding.

I agree for the most part, but own a rifle that proved the theory wrong.
I had a Marlin XL7 that I wanted to drop in a better stock than the factory synthetic garbage.
I put it in a laminate stock with an aluminum bedding insert, and everything went to crap. I fought that stock for about a year, finally realizing during testing that the barrel needed a pressure point.
So, I dropped it back into the factory stock (which has built-in pressure points at the fore-end tip), and it went right back to shooting .330s. :rolleyes:

I don't like the stock, but that action lives in the factory synthetic stock, now. (I even sold the aftermarket stock.)
Some barrels just don't like freedom...
 
Thanks! I'm not opposed to adding the aluminum pillars too but don't want to get in over my head. How exactly are these installed? I see that Brownells and Midway both sell them but I also see reviews claiming they don't fit properly. I looked up the serial number and I have a 1988 Ruger M77 with the tang safety and laminate stock. Deer season is a little over a month away so whatever I do I need to get started ASAP.
 
I've bedded about 50 rifles over the years and achieved mostly spectacular results...except for two Ruger 77s.

If I had to do a 77 again, it would get pillars made from 1/2" steel tubing and would free-float the barrel. If it didn't shoot under 1 MOA, I'd consider extending the bedding a couple of inches up the barrel channel.

Forend tip bedding would be my last resort, though a guy told me that placing a shim made from a portion of a 20 gauge Winchester AA shotgun shell cured his rifle (not one I bedded).

People have said that some of the early 77s had inferior barrels and I believe it.
 
I generally free float all my barrels and bed the front and rear of the action plus recoil lug. To bed the action, use only the front action bolt. Wrap tape around the barrel at the front of the stock to keep the barrel from pulling down and lifting the rear tang at all. Fill the rear tang bolt hole and the top of the hole in the stock. I use a drill the drill small shallow hole's everywhere I will put bedding. Like that when you tighten down the front action bolt the barrel stays up and doesn't put any pressure on the rear tang to rise. I also put a layer of painter tape on the side's, bottom and front of the recoil lug.
 
I bedded my M77 Mark II after putting a Hogue stock on it, made all the difference in the world. It'll shoot sub MOA now with a free floating barrel. There are a lot of video's on YouTube on bedding, one was even on a M77.

My Ruger M77 .243 which I purchased new about 40 years ago had a very distinct pressure point in the wood stock very close to the front end of the stock. With the advice of a very experienced rifleman, I removed the pressure point when I glass bedded the action and the surface at the rear of the recoil lug. Thus, the barrel was free-floated. The improvement in accuracy was terrific.

Edited to add: I also glass bedded under the chamber but not under the recoil lug.

I bought my Ruger M77 brand new in 1980. I still have it; it has the tang safety and also has the factory pressure point at the end of the forearm (walnut stock).

Someone "in the know" help me out here on this question: Didn't Bill Ruger and Bob Brownell work together on the design of the M77's stock back then (70s)? The angled lug bolt was supposed to pull the action tighter into the stock, and I believe that design had the pressure point feature incorporated as part of what the potential rifle's accuracy might/could be.

My M77 is in 6MM Remington. It indeed shoots very well for a hunting rifle. I haven't had to mess with anything on it, either. It has accounted for many deer and antelope in the freezer through the years, and one elk, my first.
 
The angled action screw used on those rifles don't lend themselves to tweaking nearly as much as other designs. To be honest they either shoot well out of the box or they don't. I've read of many guys who saw accuracy go downhill after floating the barrels. And glass bedding rarely helps.

Part of the problem it seems to me is that the design is so different that traditional methods don't work. Finding a gunsmith who specializes in Rugers may help. Maybe not.

Don't get me wrong, I really like the Ruger rifles. But I've owned enough over the years to know that accuracy is hit or miss with them. Some shoot, some don't. If I end up with one that doesn't shoot it goes to another home. You can easily spend more trying to get one to shoot than you'd lose by simply selling it and buying another rifle that will shoot out of the box.

I believe you, but I've never seen it in a wood stock.

I have an early '80s M77, as well as two stocks from an '80 and an '83. None have a factory pressure point. I also look at every Ruger 77 / 77 Mk II stock that I come across (for projects). I think I've handled about 80-90 'tang-safety' stocks and 20-30 Mk II stocks at this point. I've never seen a factory pressure point in a wood stock. Abnormalities, yes. But not an intentional pressure point.

I don't know if the boat paddle Mk IIs were different. Any time I see one, the price is ridiculous. So, I don't bother looking.
