Confused by .22 ammo?

[Fergie]

I have never really shot a .22 before I own several .45s.

I restored a Hi Standard Model A and on the side of the gun it reads "22 Cal Long Rifle." My friend gave me a small box of Remington Yellow Jacket 22 hyper velocity" - but it does not read "Long Rifle" on the box anywhere. When I look online the Yellow Jacket ammo has "Long Rifle" on the boxes.

I bought 500 rounds of "Federal 22 Long Rifle Target Grade Performance" rounds but they will not feed from the magazine to the gun. The box clearly reads "Long Rifle."

Did I buy the correct ammo and the rounds just wont feed because it is just one of those things with older guns? (WW2 era).

Why does the ammo that works not read "Long Rifle" on the box somewhere? It looks to be the same size as the other ammo.

The rounds look very similar, except the Yellow Jacket has a tapered bullet.

Sorry for the remedial question, but I do not want to waste money on another box of ammo until I know what I need.

I am pretty sure this is what I want...

Thanks for any help!

"The magazine lips have to be perfect for the gun to function. They run about $50 so be sure to treat them gingerly to avoid bending or knocking them out of shape."

Any .22LR 'should' work but this might be a hangup.

Just about all .22 rimfire ammunition is Long Rifle. If it is not Long Rifle, it will usually say what it is instead. .22 Short, .22 CB caps, .22 Long will not cycle in a semi-auto pistol. Neither will the Colibri rounds and some sub-sonic ammo.

.22 pistols, especially High Standards can have finicky magazines. You may need to try a variety of .22 rimfire ammo before you find something your Model A likes.

I purchased a special tool for adjusting the magazine lips on my pistols. It takes time to get it just right, but it does work.

Thanks for the links and good info! I may try the tool the adjust the magazines, or I may just buy the ammo that seems to work. I just purchased a magazine and the top is very different than the original magazine. Strangely both magazines like the Yellow Jacket so I may just stick with that.

Here is a side question...

If my rim fire .22 does not feed in properly and the slide hits the back of the rim fire round? Can it go off? What does it take to make a rim fire go boom?

It could be the difference between the power of the two rounds you are comparing.

The yellow jackets are a high power round with plenty of "kick" to cycle the pistol completely. The target rounds are most likely sub sonic or close, and thus don't have enough power to cycle the gun.

Before tweaking on your mags and possibly causing more problems, try various other ammo similar in velocity to the yellow hackets.

CCI mini-mags in either 36 gr or 40 gr projectile wt. would be a good place to start.

In this forum is an extensive discussion of ammo compatibility with semi-auto .22 pistols. Find it here:

Of course the Remington Yellow Jackets are sold out everywhere.

Of course the Remington Yellow Jackets are sold out everywhere.

Since you shoot a lot of 45 (me too), I can explain in those terms. Just about every 45 ACP pistol made can feed 230 grain ball. The guns were designed to feed rounds with that OAL and bullet shape. Some guns that will shoot 230 grain ball have trouble feeding 230 grain JHP, but most will. Others might have trouble with 200 grain JHP, and more will have trouble with 185 grain JHP. Shorter OAL and bullet shapes that are further from 230 grain ball require a much tighter tolerance in the magazine feed lips/geometry and barrel/receiver ramp. A tighter match chamber can also affect feeding.

Same goes for magazine fed 22LR pistols and rifles. If you look at the variety of bullet shapes, you can pretty easily see why some ammo works and others may have more problems. For 22LR, it seems CCI Mini Mag round nose is comparable to 230 grain ball for 45 ACP.

Older High Standards are not made to handle high velocity .22LR.Known for cracked frames especially when abused.

Would stick to standard velocity ammo. Sounds like your magazine probably needs tuning.

Wealth of info on rimfirecentral.com.

[Fergie]

Thanks for the additional info! The picture of ammo types is great and so is the warning of using higher velocity ammo - even thought that is all I can get to move from the mag to the gun right now.

Remington Yellow Jacket has a velocity of 1500 feet per second. You need to try ammo that is at least in the 1250 fps or faster in order to make sure your pistol cycles.
