Big question concerning .22-250

[OneFunGuy]

I am looking at a rifle to purchase, but need help to understand what is not clear to me. The rifle has been re-barreled with a neck chamber of .250". The standard for .22 cartridge is .2539" OD.

The seller does warn that this smaller chamber may not chamber stock/off the shelf ammo. But, he adds, this should not be an issue because the person who buys this gun is most likely a hand loader anyway.

Okay, so I can buy a Hornady Match Grade neck die in .250". Sounds easy enough until I reason that the ID of the neck will also get smaller if I squish the outside of the neck, right?

Then, a standard .2244" projectile will not fit. Right?

With this .250" chamber is the assumption that the brass must be turned? Meaning, to meet the .250" chambering requirement, you would not contract the neck, but shave the outside of the neck to .250". Is that right?

I don't have a neck lathe if that is what is required here. Of course, that can be purchased later, but it would be nice to know up front.

I have only been reloading for about 3 years, so I apologize if this is a totally stupid question.

I'd give this rifle a big time pass.

Tight neck chamber. Some benefits, but not really for the casual reloader.

I'd give this rifle a big time pass.

So would I for a couple of reasons.

First, reloading for it is going to be a pain in the tush because it's non-standard.

Second, the screaming muzzle velocities that go with that particular caliber are a bit hard on barrels, so you may be looking at a new barrel sooner rather than later, with all the complications of a non-standard chamber.

On the other hand if you're looking for an unusual project...

That is the point that your thinking gets OverThunk.

Typical standard sizing dies already "undersize" the neck. Then on upstroke the "expander" makes ID fit bullet with snug fit. So IF you have any chamber binding issue. It will be strictly OD neck related. Not bullet related.

Real world fixes if issue. Turn necks .004" after sizing "first time", easy peasy. Or have chamber neck reamed .005" "one time", also easy peasy.

Typical case neck thickness is bout .015"............004" is average human hair thickness. Ain't much. Don't necessarily need "neck lathe" like a Forester. Hand tools that index off of a mandrel also out there.

Check the Dims. in links. 22-250 cartridge neck >.254".......Chamber neck ID >.255"

If older rifle you may have a Gebby Varminter chamber. Or a Spec'd tight neck chamber for 22-250 SAAMI version.

If nice rifle, that you like, at price you're willing to pay. Don't let little crap deter you.

What is the current owner shooting in it? Does he reload?
