Weatherby Mark V (Germany) 7mm WBY Mag - 7mm REM Mag Fired Through It - "Won't Shoot Strait" - Weird Obstruction?

If you put epoxy without a release agent on the metal first it would need to go to a gunsmith. Does not mean the barrel is ruined yet, but might require a trip to a gunsmith.
Check for Weatherby gunsmiths in your area, or call Weatherby. They are in Wyoming now.

Try a small magnet on the area in question. Some epoxies are soluble in acetone.

A simple one thread set back may be a reasonable attempt at a fix.

With the history of mis-use and the cost for a gunsmith to TRY to repair (with no warranty of such repair) plus no round count or how hot the previous loads from previous owners were, just buy a Bartlein or equivalent 26" barrel in 8 twist and 3B contour and chamber for 7 WBY. Have the muzzle threaded while you're at it. Talk to your smith about reamer throat also. Berger 175Es are nice when you can find them. To me, this is the most logical solution. Appears that readily available barrels are SS or CF w/ SS less expensive but might want Cerekote instead of SS, might not.

Rhett knows what he is talking about, sound advice.
Just one last thing to check before you embark. Does it have a tang safety or is the safety on the bolt. If it is a tang safety, then it would need a bolt converstion and trigger, only done at Weatherby. If the safety is on the bolt, then Rhett's advice could be the right one.

Yep, it does have a stamp on the barrel. This morning I was able to get the factory ammo to chamber and the bolt to close but, I didn't fire it (I'm sure you can imagine). I attached a picture of the stamp.

Here's the kicker. After reading through some responses and showing the pictures from my earlier post to some other guys at work, I felt semi confident that I had a stuck case scenario going on.

As a result, I pushed an ear plug and some kneadable epoxy into the bore. In the past, I've let the epoxy set over night then, used a cleaning rod to smack the broken case out the next day.

Now that it's sounding like the ring I'm seeing in the chamber is actually part of the barrel, I'm downstairs trying to knock the clump of epoxy out. It's already proving to be very stubborn.

I'm starting to fear I may have ruined this barrel. In that case, I suppose I'll need to start looking around for a replacement.

Boy, I feel very stupid about all this.

Yeah.... I have my share of uh oh shouldn't have done that, no going back moments. I just tell myself they are wisdom building situations. I only have to convince myself.

Hey we've all made mistakes in the past so I'd not to beat myself up. I'd call Weatherby and have their smiths see if they can get the epoxy out. Like the others said their in Wyoming now, Sheridan to be exact. Manufacturers appreciate honesty so just tell them what happened and see what they can do for you.

If you feel comfortable you could try soaking the bore and chamber with penetrating oil and or placing the barreled action in the freezer and then heating it with a heat gun prior to smacking the epoxy. But honestly since it's a friend's rifle at this point I'd discuss it with him and send it to Weatherby with his permission.

Edit: If you do try to heat the rifle to release the expoxy I do warn you you run the risk of changing/ ruining the heat treat of the action. So this is why I say just send it to Weatherby. I hope this helps buddy.

Here are the two cartriges to show you that you can chamber a 7mm RM in a 7mm WBY,
I still could not see anything left in your pictures...
I will post my German Weatherby later

Just so you know-- before you go putting jb weld into any more chambers in the future--- ptg makes broken case extractors in almost every caliber --- they are adjustable and actually use your bolt and their tool to extract the broken case-- about $50 each.
Your pics didn't look like brass in the chamber to me and if there was a broken case in their then a new cartridge would not fit/chamber correctly and allow the bolt to close.
Another cheep tool to invest in is a teslong bore scope-- you could have taken a close look at the "neck and shoulder area" in the chamber.

If the past owner was chambering and shooting 7 Weatherby mag ammo without pressure signs-- I would have shot it to confirm his " won't shoot straight" claim--- may have just been a loose action bolt or scope mount bolt.

Please don't use a Dremel tool

Very Sound advice

Here are some pictures for you from a German MKV 300WBY circa 1958

I'd venture to say that the accuracy issue was due to some heavy fouling from the 7mm RM round accidentally fired. Hopefully the epoxy can be removed and there is no damage done.

I agree with you. I told him earlier, I thought perhaps carbon and copper buildup

I missed that post.
