How difficult/feasible would it be to rechamber a Remington 514 to 22 magnum? Can the action handle the additional pressure?

No, it isn't strong enough.

And the bore is too small. Most people apparently don't know it but the 22 mag uses a slightly larger bore. On two cylinder guns the bore is mag size so accuracy often suffers with LR cylinder in place.

Hard and you can buy a new one for less.

considering the difference in length there isn't going to be enough bolt travel either

so what you're saying is, other than that, it would work great??

If in fact the bore is larger there would be less resistance to the bullet, thus reduced pressure, thus less case thrust, thus, other than the bolt travel issue why not?

Edit to retract. thought process interupted.

mc223,

You have that backwards. The mag. bullet (and barrel) diameter is larger, therefore you would be forcing the larger mag. bullet through the smaller .22lr barrel of his rifle and increasing pressure.

I just measured a 22 mag cartridge bullet dia is .224 and the 22lr was .224, 22 short, .224.
22 mag bore from a slug .220.
22 LR bore from a slug .220.
These are both from Rugers.
I'm havin a real hard time finding any difference.
I pulled the bolt back on my ruger 22 LR and dang a 22Mag cartridge will sit right in there. granted there may be a very slight clearance issue if attempting to eject a loaded round. A fired case would eject easily.
I think a reputable gunsmith would better answer this, But I think it would be possible.

Well if its a Ruger I am sure it would be strong enough to handle a 22 mag. other guns are iffy though. But the chamber would need to be bored out by a gun smith and the barrel if I recall is a hair larger for 22 mags. Not much but just enough. YOu can ask a gunsmith that. But unless the gun has sentimental value, it would be cheaper to buy a new 22 mag.

I am not going to try this and yes it probably would be much better to just buy a 22 Mag. I think we may be dealing with another "Myth", re, the difference in bore sizes.
Keep it up were getting places.
And Bhk you are absolutely right if there is a difference.

It's easy to do...

Take $187 and buy a 22 mag.:uhoh:

Bore diameter isn't the problem.
Barrel rifling twist is.
.22 Long Rifle barrels are normally rifled with a 1 in 16" twist rate.
.22 Magnum is normally rifled with a 1 in 14" or 1 in 13" twist rate.

The slower long rifle twist will not adequately stabilize a heavier .22 magnum bullet and accuracy will suffer.

Model 514 rifles are gaining some collector interest and rechambering it to another caliber will kill any value the rifle might reflect.
