I had a technical malfunction in one of my M700 rifles which cause and extreme pressure problem, bolt stuck closed, empty case stuck into the end of the bolt etc.

I froze the gun and tapped the bolt free with a rubber mallet, unfortuantly the handle came off but thats a simple fix, and fortunalty I got the bolt out of the gun. The case was stuck in the bolt recess expanded to take up all the space in the recess. The lip above the ejector is bent and curled back witch resulted in a small crack on the thin metal which had previously formed the lip above the exptractor claw.

Is there anyone capable of fixing this, its a bolt from a titanium and I want to save it if I can. I'll have to rebarrel the rifle as well so I will like the action blueprinted and checked for stretch and or any damage.

If you need to see pictures just holler I can take some later tonight.

Thanks

Sounds like excessively hot ammo to me. Reloads or factory ammo?
"...bent and curled back witch resulted in a small crack on the thin metal..." That bolt is likely toast.
Welding Ti requires a very good, very experienced welder with Ti welding experience.

Titanium isn't that hard to weld, tig welding experience and you have the ability to do it. As for silver soldering, I don't know, I've never done that with titanium, but the welding isn't that hard, just make sure you don't get it too hot.
 
It's not something you're likely to be able to fix youreslf at any rate, you may as well take it in and get a professional opinion. And as long as you're rebarreling it, you may as well go with a real-deal .284 bore this time ;)

the bolt head of the 700 Ti is the same as all other 700's...plain old 4140....it probably can be repaired by soldering, and installing a new extractor.

Well there you go, pretty simple solution then. I've never handled a Ti, so I didn't know this..............but common sense says that it should be the same as the others.
 
The only part of the gun that has any titanium is the action itself. The bolt is the same as any other 700 and the barrels are made of the same stainless as all other rem stainless barrels are. You could probably find another stainless rem take off barrel of the same taper and length to replace it with fairly inexpensively.

the bare receiver is actually the only part made of titanium..the bolt is just a stainless 700 bolt with flutes and a lighter handle, looks like it's made by a powdered metallurgy process with cutouts cast into it....the bolt head, like all Rem 700 "stainless" bolts is 4140...heatreated to about 40Rc...

I do know first hand of at least one titanium barrel out there...albeit on a muzzle loader.....it can be done.

Hmmmm, very intersting, I wonder what the life of it would be compared to stainless, and chrome moly barrels. Deffinately corrosive resistant;)
 
So far the feedback I have had has been encouraging, I'm going to call some gunsmiths in the morning and possible ship the rifle away to get reworked. I would prefer to keep the remington extractor but if necessary then I'll get the sako extractor installed as a last resort. I'm sure a good machinist could fix this if he had a tig welder and built up the part that is cracked then re machined it to shape. The only problem is a good gunsmith and a good machinist isn't always the same guy.
 
Just because something _can_ be done doesn't always mean it should be done.
You make real sure you never sell this rifle without letting the potential buyer know the whole story, eh?
