Barrel Removal

[woodlotowner]

Picked up a ' Xinan' (made in China) imported to North America by Norinco at one point. It's a Mauser 98 clone in .308 Win (or so it is stamped on the barrel). Being a prudent shooter of all things Chinese, I ran the chamber gauges through this rifle to find that it swallowed the 'field' gauge with no stop in sight. I am not going to shoot it this way, of course, for fear of bad results up close and personal. I would like, however, to make a project out of it by removing the barrel and setting the head space correctly by machining (i.e. hand filing) the mating surfaces carefully until the chamber meets the spec.

I have tried already at this point to remove the barrel by loading the receiver securely in a vise, heating the receiver with a propane torch (some kind of dark non combustible liquid emerged from the seam between the barrel and the receiver during the heating process), and applying an incredible amount of torque to the barrel using a pipe wrench with a 4' pipe extension. No joy. Nary a millimeter's movement. Any ideas? I don't even know if I should be twisting clockwise or counter-clockwise. It should be apparent that I have never removed a barrel before...

At this point, with very little $$ into the rifle, I am not concerned about cosmetic implications of the disassembly process.

I believe they have a pinned barrel like most rim fires. I would not shoot it.

Thank you for the heads up on the pin design, Neilm. They were not perceptible to the eye until just now when I passed a fine file over the receiver to reveal, indeed, two vertical pins per side. Not something I was looking for at all. It would appear that this is not a repairable rifle. I'm thinking a short trip to, and an ignominious end to its life in, Davey Jones locker.

Thanks, Baribal. I'm just going to go and fondle my minty classic 1960s Parker Hale now until the disappointment with the Xinan passes.

I see they copied the old Sako trigger. Smart move there.

Mauser 98 clone, the extractor should hold the case to the bolt if you want to fire form cases using the cream of wheat method, then just neck size from there. Or is this a bad idea. Ultimately it's probably way to much effort for an old Norc.

I considered something along this line, but I'm not short on good rifles to use. Thanks.

There was one of the Nork JW105 on here that blew up first round the guy fired. Now it's a .223 which is high pressure round, but it also has pinned barrel, and the cause of the KB was the chamber had been drilled through for the pins...

Pinned barrels are also used on centerfire rifles, mostly military, and are strong enough as long as the pins are of the proper hardness and diameter. This method has been around for a long time.
