Hello everyone, quick question.... is a 22 long , rimfire barrel the same as a 22 magnum barrel. I’ve heard you can use a 22 long barrel , rechambered to 22 mag and the difference in barrel i.d. is about a .001 or .002 .
What is everyone’s thoughts. I’ve looked on other forums and it look like the Conversation turns into a huge Fight!
Basically what I need to do is rebarrel and firearm in 22 mag , I was going to turn down a 22 mag barrel and uses it as a sleeve.
I was originally black powder and want to add a little strength and a little better bore , then what was there, with a newer type of steel insert / sleeve.
Thanks for your time.
Cheers
Brian
 
Rechamber a .22 barrel to a .22 mag and it will still shoot but will effect accuracy. There will also be lead cast off at the muzzle and if it is a semi, at the chamber. If it is for a bolt there will be some stuck casings but from personal experience, all you need is a cleaning rod and a hard tap to get the casing out.
 
id welcome a 0.002" tighter barrel for shooting cast since i cant go 0.002" bigger bullets

But i deffently wouldnt go the other way. A barrel that is 0.002" too big would be terrible so id say its a no go.


Edit: it seems i read that wrong. I thought you wanted to shoot 22 LR out of a 22mag barrel.

Yep that’s what I thought...going to rebarrel an antique...not a collectors piece ,just a shooter. So the .002 might make a difference, standing in front of the right person. I don’t want to go down the no-go road...
 
Quinbrian you do not mention what kind of black powder firearm you plan to re barrel to .22mag .You will want to be sure you gun is strong enough to handle the pressure as some of them old guns are stressed ,even with modern .22 long rifle ammo.

Yep I hear ya... already did the math, should be good , I handload, and the piece will never leave me ...lol I was looking at rebarreling it in 9 mm and down loading for it, but if anyone got there hands on it and didn’t no any better... it would be a problem. Anyways 22 mag does fit... not that well, and you wouldn’t be able to put a standard 22 mag in the chamber , with out moding it , so the best of both worlds.
 
I often wondered why the 22 Win Mag doesn't have a slightly faster twist in the barrel over a 22LR. I figured with the heavier grain bullets available it would provide some additional stability when shooting a heavier grain bullet. Perhaps there isn't enough difference in velocity to justify a faster twist in a 22 WinMag.
 
You hand load 22 Winchester Mag rim ??

OK, what is the make and model of the antique gun?

Looked at your previous posts and you made mention of reworking an Iver Johnson revolver, and were looking for parts for a Stevens Marksman rifle.

Plenty of single action revolvers out there that come with both .22 LR and .22 Mag cylinders.

Yes I think the line of thought is most or all of these pistols and carbines are that they all have the larger bore of around the .223-224 range, where as a 22 shot/long will be in the .218-.219 and up to .223 for a stock run of the mill 22 long.
So they cheat a little....

Nobody is going to be shooting Cast in a .22 Magnum Rimfire, I think.

To the OP, check out Ruger's specs. They use the same barrels for shooting both Long Rifle and Rimfire Magnum in their revolvers. So, while the manufacturers who are tied down to using SAAMI specs for their stuff mostly do, there seems to be some crossover available.

While it may not be optimal, I sorta doubt that you will be doing anything wildly unsafe. Esp., if the gun was originally in a larger CF caliber. By the time you stick liners in the cylinders, as well as a liner in the bore of the barrel, you will have a lot stronger than the original, at least from the perspective of the barrel and cylinder.

Workmanship, and what the actual gun is, and it's original strength, plus condition, are really more worth worrying about, IMO. Your mileage may vary.

The was kinda , what I was thinking. With a modern steel liner, and new chamber inserts it should be a little stronger, then when it was built. But that said, I’m good with plinking at 600-800 FPS .
Thanks guys for all the great response, I think I’ve found a suitable barrel for the liner, time to get busy!
