Since it appears no major manufacturer is going to step up and re-introduce a bolt gun for the 5mm Rem Rimfire............. would it be feasible to rebarrel a .22 Mag ?? I know the length would not be an issue. But not so sure about rim diameter & thickness, etc. Anyone with an inkling of the P.I.A. factor involved in this project ??

Well, slightly off, why would you want to do that? Do you have a lifetime supply of ammo for the 5mm? I would be interested in why you want to do this. Is it more accurate?

Peter.......

The new Centurion 5mm ammo is readily availble. So, yes.......a lifetime supply would not be hard to lay in.

As for why......... I have found the 5mm RRM to be vastly superior to both the .22 Mag and the .17 HMR for killing vermin at medium to long and very long (rimfire) ranges.

I would love to have a 5mm on a better platform then the original 591 and 592. Something along the lines of the 541-T, 93 with Accu-Trigger or 77/22 or one of the CZ's would be welcome.

I'm pretty sure the 5mm runs a much higher chamber pressure than the 22 mag, or 17 hmr.
The challenge with the 5mm was building a boltface to completely encase the cartridge to handle the pressure.
This is why no one currently chambers the 5mm in the normal 882 marlin, or 22/77 configuration. No one makes a bolt face/lock up to accomodate the 5mm pressures.
Don't attempt to make a 5mm out of a 22 mag.

No intent to offend, but bolt faces (of any design) do not contain pressure in such manner as to make one style "safe" with a cartridge and another not. There was no difference in the original Remington actions that were made for the 5mm as opposed to those made for other rimfires (other than possibly length).

I would suggest that rather than technical challenges, the reason that no one currently makes a rifle for the 5mm Magnum is that there is simply insufficient demand.

If it were nothing more than cutting a chamber, and boltface, it would have been done years ago. I'm certain chamber pressures are the issue with building a 5mm on other actions. The 5mm runs 10,000+ PSI higher than the 22 mag.

stonecreek,
The Remington rifles had a two stage extractor set up that was completely different than the 22 LR versions.

If fmj flatpoints were available the switch might be justifiable. Otherwise stick with good ole 22MAG!

I've shot alot with both, and there is a noticeable difference, solids, or not.

I have a 5mm Rem, I have it because its incredibly accurate with one hole groups at 50 yards, otherwise it would be long gone...I went for years scrounging ammo here and there at high prices, then they started manufacturing it again, but for how long is my question! before it is all gone again, its a moribound caliber I assure you...

Stick with the 22 Magnum, you will be much better off..
