Hi,
I am having a problem with my old single barrel break ranger 12 gauge shotgun. This shotgun was given to me and now that i can shoot it I found that it won't close fully with a shell inserted.

I took it too a local gunsmith and he recommend i look for someone with a rechambering machine because it will do a better/cheaper job than him trying with his lathe.

the problem is that someone has damaged the surface of the chamber port. So the shell cannot be fully seated in the chamber. What needs doing is a simply clean up of the chamber port, which apparently can be easily done with this rechambering machine.

please PM me if you or you know anyone that could help out.

thanks

I am no expert but I believe you were getting bull$h!ted A lathe is all that is needed to clean up a chamber.

The real reason the smith turned down you job may be that your dented?? chamber is not reparable or not worth fixing.
 
What the heck is a rechambering machine? Last I checked, that was called a LATHE. Your guy probably doesn't have the equipment or doesn't want to do the work so is feeding you a line of BS.
 
I'm still trying to figure out what a chamber port is.

Chambering machine? Funny!

About the only thing that IS clear, is that the so called gunsmith, isn't much of one. At least not by what can be figured out in this communique.

So, as the OP does not seem to know the terminology, it may be a case of misreporting. Or he could be trying to stuff 3 1/2 inch goose loads in a 2 3/4 inch chamber.

Easy guys, he is a seemed like a he knew what he was talking about. He came recommended by each gun store i contacted.

I myself am no expert on the terminology. I just know the problem: the shotgun won't fully close and it has something do to with the shell not fitting right. It is a full three inch chamber and all i have tried to put in it was a 2 3/4 target shot. So it's not the chamber length. Just needs a clean up at the breach.

Thanks for replying
 
Where'd you get that thing from? The breech end of the barrel looks like someone slammed it closed on a handful of gravel.

A simple chamber reamer would likely be the answer, but may be worth more than the value of the gun as others have suggested. Unless it has sentimental value, a new H+R single is well under 200 bucks. A used gun could easily be found for as low as 50.
If it is sentimental, I do understand. One of my most treasured guns is a Winchester 37 16 ga my grandfather gave me.
 
I think the first issue is where is the shell binding. If that ding in the 1 o'clock position only effects the rim of the shell, you could probably clean that up with a dremel tool. I assume the gun will close with no shell in the chamber although some metal does appear to be pushed towards the breach face. If the damaged area extends into the actual chamber, as long as the dent only goes in for the first 1/4 " or so you could clean that up with judicious use of a drell tool again. Not a very elegant solution but the gun looks like it has seen some hard days and also remember that the first 3/8" (at a guess) of a shotshell is solid and does not expand significantly

You need someone with a 12 gauge chambering reamer to cut the rim true ... or an experienced smith with a Dremel tool and a steady hand...
 
.
A rechambering machine?

Since this "Gunsmith" believes there is such a thing as a "Rechambering machine, there also exists, somewhere, a CHAMBERING Machine!



That is too good to be called B.S. It has class, and should be called "The exterior by-products of Male Bovine animals."

Find a REAL Gunsmith, one who has a 12 guage chambering reamer, and have him simply hand ream the chamber to clean it up. When i did not have a lot of tooling back in the 1960s, I ended up with a 20 guage Stevens 311 double that had 2 3/4 inch chambers in it. I took it down to Elmer McConnell in Delhi, Ontario, and he hand reamed both chambers out to 3 inch in about 20 minutes while I stood there.
 
Yeah....Dunno about it being on purpose though. I'd expect to see some sort of pattern to the dents if a guy with a hammer and punch had at it.

How's the face of the breech around the firing pin look?

That looks a lot like someone slammed it shut on some steel shot, or something similar. Hard to say without seeing it firsthand.

Overall, I'd say that what you have there is a project to do yourself, as having a smith touch it is pretty much going to cost you more than it's replacement value.

Looks like a job for a sit-down with some die sinkers files and some 220 or so wet or dry paper and a collection of popsicle sticks to wrap it around. Work out the worst of the dents and the divots around the rim recess and the shells should fit, unless there are dents in the side of the chamber that are keeping the shell from seating.

Take a look at the Brownell's site and look up 12 gauge chamber reamers and you will get an idea of what the tooling cost looks like. Not worth the investment, though you can try the reamer rental places as well. Or you buy the reamer, use it carefully, and resell it. You won't get all your money out, but most...

Being completely realistic about the pressures involved, I'd not hesitate to attack it with files and sadpaper, or a Dremel tool, used with due care.

Probably the first question is "where or what part of the shell is sticking or not entering ? " If you are lucky and it is only the rim which is preventing the gun from closing, there seems to be only about ten or fifteen percent of the rim recess which is dented in. That gives you a lot of leeway because the rim recess in that area does not impact on the gun's ability to withstand pressure nor on the ability of the extractor to extract. In other words, as long as you restrict your dremel work to the area of the dent, you can be outragiously sloppy and only make the work look ugly and will not make it unsafe to shoot. (assumes the gun is safe to shoot with a perfectly repaired rim recess).

One concern with using a chamber reamer including an integral rim recess portion is that if the barrel tapers rapidly and the reamer is for a long forcing cone and say a 3' shell, you can thin the chamber in the forcing cone area, excessively. If the barrel has little taper around and ahead of the chamber, the reamer should do an excellent job

Sounds familiar, to which I would add, he seems to turn down work that he can't physically do the exact way he wants, or is comfortable with.

perhaps put yourself in the gunsmith's position; if the work is on an inexpensive gun in poor condition, does the value of the gun justify his fee and further does he want his name associated with repairs to that gun. I am not saying that the gun belonging to the OP actually meets the above description but that may be the gunsmith's assessment of it.
