What would happen if I fired a 22lr in a 22 mag gun?

Brass would bulge and maybe split. Do you wear goggles?

and it is surprising loud, bulged brass, throat erosion(like shooting CB shorts in a 22LR) and probably something bad from the lr case slamming into the chamber wall with 20000+psi.

Yep, it will fire but like Jim Watson said the brass may split and possibly fragment. Hot, high pressure gas may escape at the breech and (or) may launch pieces of the breech and you can be injured.

Also, if it is a revolver you will have MAG cases stick if you do not clean the dickens out of it.

Been there, done that. :)

I don't mean to hijack, but is it bad to shoot CB's, or shorts in a 22lr?

The projectile rattles down the barrel from not engaging the rifleing.

22lr uses a hollow/heeled base bullet so it wont have any problem engaging the rifling other than the half inch jump to first get too the rifling.

what i last read it took like a thousand shorts to do any noticeable damage/erosion so its not really bad unless you shoot a ton.

Can you point me to where you read that? I'm kinda concerned now. My Heritage rough rider gives me nice, tight groups with these.

if a quanity of shorts are fired, because of the shortness of this round compared to a long rifle....the bullet actually slams into the chamber as it hits the bore`s rifling. Continued (bunchs) of shorts fired in these rifles, eat away good metal in the end of the chamber, where a long rifle would seat. This continued slaming against this area, along with powder flash, eats away metal over time (Throat erosion). It`s just something to look for, as it can ruin accuracy.

googled it lol

The only concern is with rifle barrels, CBs could cause the projectile to get stuck in the barrel. They only use a primer to propel the round. I've never seen it happen though.

That's what I've always heard since I was a kid and that's why I was surprised to hear that it's a problem. After Google-ing it I did come across this:

"Back in the day of black powder cartridges and corrosive priming, excessive use of .22 shorts could erode the chamber just ahead of the .22S case mouth,"

from http://www.odcmp.org/new_forum/topic.asp?ARCHIVE=true&TOPIC_ID=55610

Maybe what 1858 Remington quoted was an article talking about black powder shorts?

I don't mean to hijack, but is it bad to shoot CB's, or shorts in a 22lr?CCI (and I am sure others) make CB longs. The case is the same size as a .22LR. The bullet is a little smaller so I don't know how well they would work in a semi-auto, but they work great in my Single Six.

Here they are side by side:

I have a S&W 351pd. What would happen if I put 22lr in it?

Just exactly what they said would happen in the first five posts.

Lots of smoke, noise, leaking powder gas, and bulged or split cases.

Not to mention that the smaller rim of the .22 RF will not get a solid hit from the .22 Mag firing pin location.

but is it bad to shoot CB's, or shorts in a 22lr?
No, not since black powder corrosive primer days.
And that would have been O.K. then too if they had cleaned thier .22's once every blue moon.

You & I won't live long enough to hurt a LR chamber shooting shorts in it.

I'm having trouble finding 22 magnum to shoot in my 351pd. I have some. Just don't want to blow off the last of my supply.

Well, I'd keep looking.

Shooting .22RF in a .22 Mag is bad Juju.
Don't do it.

you can also shoot 22 wrf in a 22wmr gun. wrf is a 22lr length and powered cartrdge that uses a non heeled bullet.

maybe i ment shorts then...... cci makes some called CB Shorts and they DO have a powder charge and are fairly fast but quiet. remington golden bullets are like that also, onlt about a half inch long and 800 or so fps with a 20something grain bullet.

"...projectile rattles down the barrel..." One thou difference in bullet diameter won't cause the bullet to rattle down the barrel. The difference in case diameter isn't good though.

I hear tell, but have never tried, that one can grind the base off a fired .22 mag case, insert a .22LR cartridge inside it, and then safely fire the .22LR in a .22 mag chamber. Can anyone say yay or nay?

cci makes some called CB Shorts and they DO have a powder charge and are fairly fast but quiet I was actually thinking of Aguila Colibri Hummingbirds. I've heard some folks refer to them as CBs. I might be incorrect in considering them the same thing.

Legionnaire,

Doesn't sound like a good idea to me. Let me know if you try it.


Did you know you can use a bore cleaning brush for a ruptured cartridge extractor? Works great!
