At some point you may find that to get the level of accuracy you want will cost you more than what you are willing spend. How well do you want this rifle to shoot?

At a minimum, I'd like consistent 1.5" groups since Weatherby "guaranteed" that. It would be nice if I could come closer to 1".

I'm not averse to investing in this project, as long as I have some confidence that whatever I do will help.

If the rear tang is up 1/16th and you haven't removed the up pressure in front yet that's telling you you never had any. Os for the barrel keeping on creeping over, sounds like the action cutout is not straight. As you relieve pressure on the side of the barrel channel it's allowing the stress in the action cutout to relieve a bit. Next, when you push down on the rear tang the front of the barrel comes up and left. It's the left movement that's telling you where the pressure is. Go into the action area and sand the left side of the cutout bur don't hit the bearing surfaces for the rear tang and the area under the chamber. Do get the area at the sides of the chamber. Also check and be sure that the area around the sides of the rear tang are free. Don't need a lot of clearance, just enough to be sure that's not pushing the barrel over.

Read back. Vertical stringing is generally a sign of receiver bind. Now with the barrel free that's exactly what your seeing when you push the tang down and the barrel moves left. With no receiver bind, the barrel should lift straight up. Your getting very close as a major culprit has been discovered. Pretty bad factory bedding job!

Don't give up yet, your very close. Matter of fact, that up pressure they say you have in front, take it out. You can always put it back if you want with a bit of epoxy. I don't think you'll want to.

Hey, Don...just for clarification, I believe what's happening when the action rests in the rifle is that its primary contact point is the front lug. I think gravity is causing the barrel to pitch forward slightly until it contacts the stock, and that's why the rear tang is up a bit.

I did end up relieving the upward pressure in front, since I figured I had no way to ensure it wasn't canted, and the 1/16" went to about 1/8" which is evidence of my hypothesis above.

I'll go downstairs in a bit and tackle the action part of the stock. If the wind dies down, I can shoot this afternoon and report back this evening. Thanks for all the help.

One thing: if receiver bind is pushing the barrel left, wouldn't the bind be on the right side of the receiver?

The "bind is on the right but the material would need to be removed from the same side as the barrel is moving in the action. Since the barrel is being "pushed" to the left that means that ,in the action side, there is too much material on the left. Kinna like siting in.. Chase the bullet

mzimmers;

Your 1.5" group expectation is realistic. No reason a good rifle should not be able to do that. I see a lot of hunters think that they have a bad rifle because they can't get it group under 1". Hunting rifles generally are not made to shoot that well nor do they often need to. The only shot that really counts is the first one. If you put it where it needs to go, group size doesn't come into play.

Then again, what fun is it to go to the range with a rifle that won't group?

I doubt it. What is happening is that the action is coming down and being pushed right from the left side. Then it is pivioting at the contact point nearest to it, the front lug. That pushs the barrel in the oposite direction, left.

I agree with JC 100% if it's a good bolt action you can improve by hand loads glass bedding etc , i've had mine done years ago and it still groups under 3/4 inch at 200 yrds , I use weaver low mounts and had the rifle custom fitted for my reach among other things the way I check the butt length is hold the rifle along my fore arm with the butt resting in the folfd where the elbow bends ,your trigger finger should line up directly with the trigger i trimmed an inch off the butt and replaced the butt plate i had a test done on the amo and found the best load for my gun i use 100gr nosler balastics tips the formula i keep locked up in my gun cabinet i use the same round on the range as i do for hunting i changed the barrel to a higher end scope barrel had the end camfered inward for a self cleaning action adjusted the trigger pressure and installed a trigger shoe then i invested in a a harris bi pod my barrel is also free float

Hey, guys -

I decided to put a bunch of pictures up on a gallery. (This topic is becoming worthy of a blog!) Here's the link...the pictures and their captions pretty much tell today's story. Follow the link and select the Weatherby .240 album.

Let me know if you have any troubles with this...it's my first time. Thanks, all...

In the detail of the action lug opening, what is that dark wood in fromt of the lug?
