Barrel overheating question.

[BoydAllen]

A couple of other bedding things...
Action screws should not touch the stock. They should only touch the floor plate or escutcheon, and trigger guard and action. There should be clearance between them and the stock. Another thing is that there should not be any vertical surfaces that are bedded so as to create secondary recoil lugs. On the stock shown, that back of the tang should have clearance, and any other areas that would restrict rearward motion. Only the back of the recoil lug should perform this function.

Is that barrel machined like that?

If your referring to the diamond patterning.. that's just a sand-blasted surface treatment.

Otherwise Im not sure what your talking about.

Allen,
I have seen gun smiths put tape on the face of the lug and bottom when bedding but I have also seen them put it just on the bottom of the lug.
Does the recoil lug need to move-and if so how does it work with guled in bench rest rifles? :}

First of all, all of this talk of dollar bills and clearance is antiquated. I would be looking for a sixteenth of an inch, minimum, for a target rifle, all the way back to the action. The other thing is that you cannot see if bedding is correct by looking at it. It takes a dial indicator and a magnetic base, or something similar. Bedding can look good and be bad. Third, what shape are your groups? Are you using wind flags? What sort of rest and bench? How are you holding the rifle? Erratic results can happen for a number of reasons, and easily be diagnosed as to their cause. I am not trying to pick on you here, just to bring up some issues that may shed some light on potential sources of your problem. Good luck. If you figure out something that works, let us know. One more thing, light loads with some ball powders can produce a ton of fouling, pretty quickly, and one more question. How do you clean?

(Thanks for the ideas, as I'm really learning.. there is likely lots I'm just confused on)

The shape of my groups are triangulated. However frequently I will have 2 round touching and then a flyer. I admit I don't use wind flags. The rest is a Caldwell Rock Front Shooting Rest and rear bag, the bench is a concrete stand and top provided by the range.

As for holding the rifle, I do my best to have consistent cheek weld in the same position, have my trigger finger (just the tip) on the trigger. I pull back so as to have a singular angle and not induce a bend with my finger - even pull. My non trigger finger is wrapped under the stock grabbing the bag to make minor adjustments.

As for loads, Varget has worked the best for me (I've tried 2 others) and the charge is .5gr. off the max. 45.5 for 308 WIN.

As for cleaning, I use Hoppe's #9 solvent and a bore snake. Once a month or so, I will clean the copper out with bore tech CU+2

Most "glued in" BR rifles do not have recoil lugs, other than the rear of the tang.

I will check again, but they appear to only touch the threads in the action and the floor plate. I will check the stock again.

 

[kritos666]

Two things.
Fist is I have been told by 3 Different smiths that they have not had good luck in the past with the stock being bedded pass the lug.
Second, I had a rifle that was like changing POI and the bedding to me look great. So i let Robert Gradous take a look and the rifle and it was moving in the stock. I mean moving very very little movement. He rebedded the lug and it fixed the problem.
Also I knew a fellow shooting a 308 that had a problem kinda like your and it was the action bolt touching the threads on the barrel. He shorten the screw and was good to go.

It sounds like it might be time to find a precision gunsmith in Oregon (where I'm at) Not only could they check the bedding, they could check to bolt face as well. From what I am gathering.. I'm starting to get into things beyond my knowledge or ability to confirm or deny.

Excuse my ignorance but what kind of action are you using and also what type of bedding compound?
