Finding a new full length barrel for a Ross M10/Mk3, is that even possible?

[greenoliver1]

Picked up an M10 Ross a while back from GP and had extraction issues from day 1. I’ve now discovered that the chamber has a bunch of small pits inside it. It has the “EC” marked barrel. I wasn’t sure if it could be reamed slightly larger to get rid of the pits, or if I needed a new barrel. Did any company ever offer a full length M10 barrel aftermarket like Criterion? I wouldn’t mind having a newer one in better condition so the life of this old rifle could be extended.

I'm a long, LONG way from a Ross expert. Plenty here know more than I do. But if I recall correctly, one (or more) subtypes of the Ross used a square thread to attach the barrel to the receiver, and this has made rebarreling somewhat burdensome.

Is this an issue with the M. 10? Dunno. But if it is, perhaps that makes rebarreling more trouble than most are willing to go to.

Here's an '05 barrel with the threads in question:

Would it be possible to cut the barrel back one thread, reinstall and then hand turn the chamber with a reamer enough to give the correct headspace (and clean up the chamber)?

A Mk.III/M10 rifle breech has conventional right hand square threads. The breech is rather large in diameter. The barrel is quite long, as well.
I do not know if replacement barrels have been made.
A custom barrel would be possible. It would most definitely not be cheap. Long blank, custom contour, .303 bore.

A pitted enlarged chamber could hardly be reamed larger to get rid of pits. Even setting back could be problematic.
Is the rifle sported or as-issued?

Another option would be to ream the chamber out to 303 improved. Should remove any pits and barrel should go back on and line up properly.

An enlarged chamber can be pretty ugly. I wonder if even an Improved reamer would clean it up.

I’ve looked and never seen a mention of them being manufactured “on mass” if you will, seen a lot of state side folks saying they went the custom route. Rifle is full wood, but it’s not its original stock. I was told it’s an Indian Curry stock as there’s the cut-outs for a chamber pin. But the wear in the finish makes it look like it’s sported a full length stock its whole life. There’s a Serial Number on the right side of receiver marked “M106xx” while the stock has a “537” over 1917.

I think I got screwed in the deal so I’m just trying to make this into a shooter. It’s a shame because it looks beautiful.

You might be able to find a barreled receiver/barreled action/sported rifle and set up something with a shootable bore.
Getting a barrel made and installed would not be cost effective. Doubt that a barrel could be made and installed for much under a thousand.
Those notches in the Indian DP stock - I've seen semi-circular patches fitted. Poor appearance, really obvious why it was done. A better solution is to do an armourer's style repair with rectangular pieces inlaid.
My "shooter" Mk.III is a barreled action from a sported rifle set up in an original military replacement stock. That stock was a rare find. And getting a nosecap was a trial.

I’ve been trying to get hold of you a few days. I’ve got a solution. I’ll be home briefly tomorrow night and can send you pics on messenger.

Email K&S Arms in Edmonton, they can make you a barrel if you want.

Give'r the Cooey Carcano trick. Cut it off and thread the stub... don't forget the locking screw to mess with the Normie's heads.
