Ruger M77 MKII Shot Stringing

[Longranger]

So I have a ruger m77 mk2 in 30-06 with the sporter profile barrel. I can only seem to get the first 2 shots to group and all of them after that start stringing vertically. The first 2 shots are easily sub moa but the rest are inches high usually. The barrel is free floated but not bedded. Just wondering if anyone here has m77 knowledge and whether or not this is typical of the thin barrels? Or if there's anything that can be done to get more shots before it starts walking?
Thanks in advance!

Yep

I had one with a SS barrel and it would start walking on the 3red shot if I didn't allow it to cool between shots. You may need to do the same. Don't be afraid to use a water soaked towel on the barrel to aid in cooling.

Lol yeah, it's a hunting rifle but I wish I had at least 3 or 4 before it starts walking. I have a Savage with a pencil barrel that I haven't shot yet, do they seem to do any better?

The only Savage I have any experience with is my Axis 22-250. I often shoot 5 shot strings without issue. I let it cool after each 5 shot string.

I had a Ruger 77 in .270 Shot tight then started throwing them
high and right, about in a perfect arc. Had it bedded, and settled
it right down for the first 5 shots at the bench. After that, the
barrel was too hot.

Rugers can be finicky but I have found that if you put a little fore end pressure right at the end of the stock things will settle down nicely. I generally add a little bedding as I bed the receiver or you can just use a folded up piece of paper slid underneath just to test it out.

Interesting. From the factory it had a major pressure point at the end od the stock pushing upward on the barrel and it strung shots the same way. So I free-floated it and nothing seems to have changed. But I'll have to play around with the folded up paper like you said.

Noted. That's probably what I should do I've just been hoping it's something simpler.

I had a $200 axis as well and it shot just like yours. Didn't like the bolt throw on it though. Frustrating that the ruger that's worth 3 times the axis does this. The ruger is actually quite a bit more accurate than the axis for the first two shots but then it opens up wildly.

I put in a Timney trigger and installed it in a Boyd's At-One thumbhole and it is now a 1/2 moa gun to 400 yards. The only rifle I have that it won't outshoot is my Sako 300 wm.

The biggest problem with the Rugers was the angled front action screw. You cant pull things in 2 different directions without getting stress.

LOL wow maybe I should kept my axis, have you had the same experience with the sporter barrelled savage 110s in the cheap plastic stocks?

Not sure I understand, What's being pulled away from the direction of the angled screw?

Yes! The plastic stock have too much give and flex. A stock upgrade will make all the difference.

The angled screw pulls the action down and to the rear at 45 degrees, while the other screws pull straight down, hence 2 different directions.

The angled screw was an exceptional idea I always thought. People always rip on Ruger for that but when properly pillar and glass bedded it is probably one of the most rock solid setups going. I have a couple of Ruger M77 rifles and they are some of the most accurate I own.

Are your m77s sporter profile barrels? How mnay shots do you get before getting heat walk?

Well ruger suggests the non-angled screws being only barely hand tight, I assume to prevent or minimize this.
