Short or LONG



Log in to see fewer ads
Browning 22 auto
08504PM146
Made in 1980 -- I think --
How do I find out if it is a short or long rifle ??what are differences -
Parts show both -- doesn't seem to want to feed LR - can parts be changed to feed ???
Thanks

Unload the gun please.

On the barrel it will say ,on the left hand side as the gun is point away from you, eithe 22short or 22 Lr.

You can not put one into another. If it shoots shorts it will not shoot longs. In order to switch youíd have to change a lot of pats , a lot.

Not worth the time money or energy,not withstanding the fact that by doing so you would be ruining a beautiful firearm, and potentially setting some one else to get hurt.rifles have the caliber marked on the barrel so the user wonít put something else in there that doesnít fit and blow up the gun their hand or their face.Rimfires are particularly dangerous because the primer, thatís the part that ignites the gunpowder is in the rim, not in the middle like centerfire. So anything slamming into yer rim can set them off.

Look at the breech block. The short version is a lightened version of the .22LR version, Here you can see what they look like:

Now that I donít have to worry about you hurting yourself. If it shoots shorts it wonít shoot longs and visa versa. How do you even know itís a browning and not a norinco?

Shorts and LR use bullets that are the same size, but the Short brass is shorter. Longs and LR use the same length brass, but the bullets of the Long are shorter. The diameter of the bullets and brass are the same for all 3, but the OAL for each is different.

If you lock the action open and drop an LR round into the chamber with the muzzle pointed down, it should fall all the way in if it's an LR chamber. The round will stop short by a little over 1/8" if it's a Short chamber.

Shorts can be fired in S, L, or LR chambered barrels. But the accuracy will be worse in the longer chambers because of the increased jump to the leade of the rifling. Also, carbon deposits from Shorts will start further back towards the breech if fired in the longer chambers. So the chambers will need to be cleaned well before going back to shooting the longer rounds.

What you never want to do is try to fire L or LR rounds in a Short chamber. OOB case splits, or much worse can result from excessive chamber pressure.

Even if it does have an LR chamber, it's possible the action is for Shorts and someone only changed the barrels. This will allow you to shoot LR in hand loaded single shot mode, but rounds won't feed from the magazine. The action would need to be updated to LR as well.

Good luck getting it sorted out!

A LR breech block will have flat sides.
A short breech block will have relieved hollowed out sides to make it lighter.
The caliber is not indicated within the serial number.
Unusual that a custom barrel would not be caliber marked by the gunsmith.
The cartridge follower on the inner magazine tube will be shorter on a short gun as well.
A short barrel will also have a slower rate of twist. It won't be 1:16, as found on a LR.
