Why are most .22 magazines curved like a banana??

[sewktbk]

I've been wondering this for a LONG time. May be a stupid, unecessary question, but i remain curious.

I don't get why a lot of hi-cap .22 mags (10/22, remington, etc) are so damn curved like bananas.

Why don't manufacturers make mags that resemble the MP5 mags, like the marauder mags, for example)??? All rimfire rifles would look so much better IMO..

Is there a reason behind the extra-curved ones?

I know. First world problems.

Just a guess but maybe it helps in preventing the mag to be too long?

Ya gotta rim on the cartridge.

i always thought it was just to make it feed better since one end is fatter than the other and it naturally forms a curve as they stack.

Just like .303, and 7.62x39.
Rimmed cartriges. Fatter near the rim. Makes a curve.

Yes, the rim on the case is wider than the bullet, so unless you point them both ways (not recommended), a stack of them is naturally going to curve like a banana.

 

[Max Relax]

Because it gives them "appeal"...
Ha Ha Ha Ha... I am so alone...

I thought about that, but then again, look at the .22 mags for the GSG5...or the .22 mags from promag for their marauder kit...

Negates that argument really.

You may find that the outside is straight but the inside feeding path of the mag is curved on some models. On other models the curve is still there but is reduced, as a resault the ammo sits in a somewhat unnatural position within the mag.

Gevarm, Voere, Mahely and Squires Bingham mags are the only straight Hi-cap 22's i know of.

7.62 x 39 are rimmed? Mine sure don't look rimmed...

Actually, the Squire Bingham 25 rounder I saw had a curve to it.

 

[crosman177]

I've never seen that one, just the 15 and 10's. Cool to know, seem similar to the Puma/Pietta Wildcat pps50.

He did say "fatter near the rim" after wards and the 7.62x39 does have a heavy taper. Refresh my memory. What does a dragonov mag look like? The 762x54R has a tapered bottel neck rimed case.

It has a very slight curve forward to it.

A better question, I think, is why .223 mags are curved while .308 isn't. I didn't think .223 rounds were tapered?

 

[lone-wolf]

20rd .223 mags are straight.

I'm going to guess that the spring needs to do less work on a curved magazine, so that is why the 30rd magazine for the AR are curved.
That, and takes up less vertical space.

 

[legi0n]

Ruger Mk3 22/45 has straight mags. Mk2 has straight mags too.
So there's no (engineering) reason to have them curved.
Not a rifle though.

 

[fnrob]

True, though technically, those are not straight mags - they're slanted rearwards, which is another way to make magazines for a rimmed or tapered case feed the rounds reliably. The Buckmarks, Hi-Standards, Beretta Neos, Colt Woodsman, etc. are other examples.

you cant have a high capacity banana clip without a banana shaped mag.
