Could the stock be putting too much pressure on the barrel?

Well, that was my first thought all along...that's why I wanted to relieve the stock a little, but the folks at Weatherby told me not to.

It could also be your technique. Be sure to use proper breathing, trigger control, sight picture, follow through, and no cant. That is not to let the rifle tilt right or left while shooting it. Also, be sure your platform is as stable as possible and that your neck is not positioned too high or low on the stock.

I'm sure my technique is less than perfect, but...I'm sitting ona very stable bench, using good rests, and one thing I'll say for myself is I don't flinch.

Stock fit is always a problem for me, as I have a long neck, but...I really don't think that's what's going on here.

As a guess, all the group's indicate maybe a bit of reciever bind. Notice rvrn with shots 7 thru 10, if you pull them together, they string vertically. Could also be stock pressure in front of the chamber. My barrels float from the fore end tip to the action. The only bedding is the action's. Except one old custom I won't fool with. Weatherby says don't fool with the stock. Thin barrel with up pressure at the tip? Can you run a dollar bill around the barrel like a shoe shine rag and easily slide it to or near the action?

Hey, Don –

I just checked the barrel, and there is virtually no space between it and the stock. I can slide a dollar bill into the frontmost inch, and there's a small space further back on one side, but that's it.

I'm really willing to ignore Weatherby's advice (they really haven't been that helpful). Should I get a dowel and some sandpaper and gently relieve the area where the stock meets the barrel?

That would help a good deal. Work your way all the way back thru the barrel channel. Using a dowel will be prettier but I hog it out with a dremel tool then clean it up with sandpaper. Be sure to refinish it when your done. Keep in mind it's better to have to much space there than to little. When I'm done I can slide two business cards under it all the way. After you do that, check for bind in the reciever. If it's there, and I suspect it is, it will be easy to detect.

OK...I'll get started on it right now.

What do you mean by "receiver bind?"

The reciever has to set flat in it's cutout or stress is put on it. Often recognized with the verticle groups you have. Tighten down both guard screws and hold the stock at the forend tip, rest the butt on the floor or table. Your fingers at the forend should be lightly touching the barrel to feel for movement. Sometimes there's so much you can see it. You simply lossen the front guard screw and bimd in the reciever will raise the barrel out of the channel. Keep an eye at the chamber too. If theres a bind and with the fit in the channel now, the barrel may not rise at the tip but the action at the front may rise up. In either case what your seeing is the bind in the reciever being let loose.

If you visualize the reciever setting in it's cutout, the rear tang and flat under the front should be in contact with no pressure on the barrel. There should also be no pressure on the sides of the reciever in the middle. If there is, it might be holding up the reciever out of the cutout and pulling it down flexs the rear tang creating the bind. The recoil lug should be in full contact with the stock at the back of it's mortice but should not touch at the bottom or sides. Easier to detect these things than it sounds. Take one at a time. Start with the barrel channel and get it floated. Do that and let us know what happens.

OK...I just sanded out the barrel groove to the point where a dollar bill (but not two business cards) can slide easily from the front of the stock back to the receiver. That was a surprising amount of work. I hit it with 80 grit and then with 150. I haven't put a finish on it yet, since I imagine I may be taking more material off soon.

If I understand your explanation of receiver bind, I don't think I've got that going on with this gun.

Anything else I should do, or is it time for another trip to the range?

You could go to the range. If the weather is nice take the gun as is. Give it a try and let's hear. Before finishing it, you might want to let the barrel channel out a bit more. It's possible the cleaning of the barrel channel could remove any action bind. If the wood was a bit high under the chamber, removing it to where the dollar slid down actually would drop the front of the action into solid contact. If the rifle shoots well, I'd still bed the area behind the recoil lug, front of the action and the rear tang. Let us know.

Hi, guys -

I recently bought a Weatherby .240 online. I went in with my eyes open, knowing the barrel might have been shot out, and it turns out this may be the case. Lousy groups and slightly low velocities are the symptoms.

My problem is, there are really no decentl gunsmiths within what I consider driving distance to me, and, while I'm willing to send the gun somewhere for rebarreling...I don't want to do it unless I know the barrel is bad.

It's been suggested that all it might need is a bedding. Again, I don't mind having this done, but only if I know the barrel is OK. It's kind of a catch-22. I guess what I need is someone who can diagnose the problem for me, and/or then do the necessary work. Any suggestions?

I hope this wasn't too rambling...I'd appreciate any input.

...Your barrel may very well be no good if the previous owner never cleaned it and stored it dirty , but before replacing i would check the barrel for any damage like a swelling spot or ring if you run your hands a long it you may even feel it , then for sure i would try the handloads provided there done right by someone who has experience and a good set of scales the first thing i do with a new gun is have it bedded , then i would consider a new barrel Thumbs up

Hey, Don -

I did a little more relief on the stock today; I can now slide a piece of paper that's .024" thick without it binding, except for the foremost 1" or so. I remember Weatherby telling me that these small-profile barrels do better when they get a little upward pressure at the tip; should I leave it as is, or is this sort of an in-for-a-penny-in-for-a-pound things?

I can finish up the work tonight and test it tomorrow, probably.
