Barrel threading pattern standardized?
Is it convenient to install a Remington barrel on a Ruger action? I suppose the question is whether there is a standard thread pattern on rifle barrels, or whether the thread pattern is manufacturer specific. I'm totally ignorant on the subject and could use a quick overview of the situation.

Thanks

Can't be swaped, can be recut and chambered

In short, very few manufacturers share the same threading specs. Many will have a 16 TPI thread but the diameter will vary. And, on those that may actually share both TPI and diameter, the length may vary.

Figures. Thanks for the info.

Yes.....and then to make matters worse the Remingtons are counterbored to achieve one of their three rings of steel.

and then, to make matters worse, if you use a winchester action you have to make a cut out on the end of the coned breach for the extractor!

Apparently depends on a persons perspective.

I'd say, then to make matters worse the rifle SAFER for shooting when a Case Separation could occur, the Remingtons are counterbored to achieve one of their three rings of steel

Hot core, I'm not knocking the Remington action, I'm merely keeping in the context of this thread discussing the standardization (or lack thereof) of barrel threading and why one can't be used for another.

My point being that even if another company used the same thread as Remington the counterbore would still need to be removed to exchange the barrel.

Standardization of threads is not likely ever going to happen with so much variation and 22WRF discussed the coned breech and extractor cut.

Also we might add the (almost) Acme threads on 1917 enfields and '03 springfields.

One can rest assured that once a barrel is removed, the (probable) only place it can be used is on another action of the same make.

Is that some “technical term†for square threads? Smiler

Unless like the '03 springfield barrels, you recut the thread and rechamber. Many barrels are adaptable to other actions, most however will not just screw on. In fact most barrels are not what you'd consider plug and play even on other receivers of the same make & model.

For what it's worth Ruger M77 & win M70interchange but of course you have to headspace.
