Cooey Carcano 6.5mm x 54?

#2 above...too late and I can confirm that it is a press fitted barrel, futile to try to remove.

It may seem to be a press fit because it's fully seized up, but I can assure you that every Cooey-Carcano has an Austrian barrel THREADED into the adapter, which is made from the stub of the original. The set screw was merely a belt-and-braces precaution that, as you've discovered, was unnecessary. I've taken several apart over the years and none of them gave up willingly! Check this link for photos:

That's my thread - it's the same "Andy" in both forums.

Here's a pic of the disassembled barrel.

This is what the few if them i have taken apart look like. I have one of those threaded stubs in hand now, and using one of the barrels rechambered to 6.5x53R and a new barrel stub on a LE build. They feel seized on there. But threaded not pressed.

Well thanks a lot guys. You were correct in that the barrel is threaded. The threads were just so fine and the transition piece was so tapered it was difficult to tell that it was coming apart as I was turning it. It appeared like it was simply turning like a press fitted item. Your persistence in telling me otherwise made me reconsider, here are the pics.

Here are a couple pics of the 6.5MS brass in the barrel. Does this look correct to any of you? The brass seems to fit in the bolt and extractor as well. However when it was together it still didn't seem to fit correctly. I'll be cleaning it up this weekend and putting it back together to give it another go.

That looks like too much case head projection.
The breech face of the barrel looks a bit gnawed upon, rather than cleanly faced on a lathe.
I wonder if someone hasn't had a go at it. Perhaps tried the rifle with 6.5x52MC ammunition, noted signs of excess headspace and tried to set the barrel back?
 
Sorry Andy! Didn't mean to double-post on you. I didn't check the photo link in your earlier post, I just copied it from my Cooey-Carcano file. Good to see you're still on the job! :wave:

I'm happy that what I contributed 15 or so years ago still has some use. It stopped being "my" stuff when it was posted, it's now public content.

Goes to show that "new" questions and discoveries have likely all been done before on CGN. If people learn how to use the search function and you look around a bit, there's a lot here.

I'd say the same thing - if the cartridge projects past the case head too much, or has very little case head supported by the barrel, you'll get bulging, and if really excessive, possibly blowout. This looks borderline depending on the brass, but a couple of turns of a chamber reamer could correct it, then with the "Savage-like" headspacing adjustment done you'd re-drill for the set screw and reset your front sight unless one compelet turn of the barrel could be used.

That's how I found your posts, and on a couple of different forums. For me, the big downside of searching is that I pull up posts from five or ten (or more) years ago that I'm dying to address, but I'm too late to the party. I've actually PM'd people about their old projects, if they're still active members, and I've learned a huge amount from them. The really hard part is when you find someone who's the go-to authority on a particularly interesting subject and you'd love to ask him a slew of questions, but his posts abruptly stopped several years ago....

I hear ya - I miss the wisdom and humility of "4831" who passed away a few years ago, but his posts live on.....
 
armstrong3j: If worst comes to worst and you decide to rebarrel, you can simplify things by threading directly into the receiver (it's roughly 1 1/16" x 14 t.p.i.) and dispense with the adapter entirely. And if that happens, I'd be happy to buy the old adapter from you for one of my projects.
 
Should you decide to rebarrel to 7.62x39, a Lee Enfield barrel works nicely.
The front end of the .303 chamber is just about the same as a 7.62x39 chamber. Some folks have used it as is. Turn the barrel shank to the diameter of the 6.5 barrel, thread it and shorten it. Set the headspace. Direct replacement for the current barrel.
Should you go this way, steel cased surplus may give extraction problems, compared with brass case.
Your barrel could be refitted. That is going to need a reamer. Unless the bore warrants the work, I don't know if this would be practical.
 
Thanks guys. I have a guy I can bring it to that is a gun smith. Will be showing him some of these suggestions and if I don't think it is worth it will be parting it out. Will give the pieces away as I would rather they find use then the garbage. Will be posting back here when I talk to him this coming week.
