A 22lr mystery (for me at least)

[7.62 Nato]

you guys the 22LR has been around for over a century and the WMR has been around since the 60's and the kaltec came out last year, so the 22 high cap is like the most advanced bit of rimfire tec out there

And the Grendel P30 was made between 1990-94 until the assault weapon ban. And guess what? The KEL-tec PMR30,and the GRENdel P30 were both designed by George KELLGREN. George Kellgren is an owner and Chief Engineer. He is the Swedish designer who also designed many earlier Husqvarna (in Sweden), Swedish Interdynamics AB (in Sweden), Intratec, and Grendel brand firearms. According to the ATF[2], Kel-Tec is the third largest handgun maker in the U.S.

Why on earth do 22lr semi-auto pistols only hold 10 rounds.

The standard course of fire in a target match is ten shots per target for score.

I bought my Ruger Mark II as a target pistol (also serves as woodswalking sidearm) and I suspect the largest market for full-size .22 pistols is target shooting and to a lesser degree small game hunting.

ok so maybe the p30 is not brand new tech learn somethin new every day, But i do know i wish i could unlearn about that Grendel, that thing looks like some sort of nightmare

But she'll dance all night long. Don't knock it until you've tried one. I prefer it to the PMR30 except for the sights. The PMRs definitely jump out at you.

I've kinda gone in the other direction, and download my magazines to five or six rounds.

I shoot a .22 pistol primarily for center fire training, so I want to practice changing magazines.

Kodiakbeer, if you intend to use the extractor hook as an anvil that's going to come with a lot of problems. First of all the extractor will move somewhat and that'll remove some of the impact force. Then there's the issue of that rather delicate extractor hook being beaten on by the firing pin forces. Finally you're now tring to pack both the firing pin and extractor hook into the same place in the slide. That's a lot of competition for the real estate in that area.

The usual way to get more RF rounds in a magazine is to make it wider at the back. That allows the rounds to stack better, but there is a limit. There have been large capacity .22 LR magazines, holding as many as 50-100 rounds, but they were more on the order of "to show it can be done" than anything very practical for a conventional handgun.

Isn't the 25 acp in essence a rimless 22?

 

[Shadow 7D]

Um, actually it was to 'solve the ignition issues and magazine issues' of the .22 rimfires, so YES.

It's just harder to put rimmed cartridges in a magazine. That's why most .22 handgun magazines are designed with such a steep angle to accomodate the overlap of the rimmed cartridges. My new Ruger SR22 has an interesting magazine, it's still a ten shot mag but almost a vertical design. The rimmed ends of the cartridges are staggered sideways while the bullet ends are sitting inline. I hadn't seen a .22 pistol magazine set up that way. It's considerably shorter than my Buckmark ten shot magazine too which seems to be the reason for the odd stagger in the SR22 mag. If the pistol's butt was a bit longer it looks like that setup would work for 15-20 rounds without getting too long. It works well in the SR22, I've sent about 400 rounds through mine without a single problem.

But what if the rounds are single stacked at the bullet but staggered to a double stack setup at the back? The side to side staggering would compensate for the larger diameter of the rims. And of course the last 5 or so rounds would rise up through a tapered rear section of the magazine to arrive in true single stack condition at the top.

I don't recall which gun it was but I've seen this on a rimfire magazine at some point in the last year.

This magazine is manufactured by Phoenix Arms for the $120.00 pot metal HP22A. And it's absolutely brilliant. The gun itself is a good design with some manufacturing issues. But after a tune up, and as long as I don't rub the slide or run into a dud, this gun is utterly, stone-cold, 100% reliable. It's incredible. I've had way more jams on my MkIII (about 3, which is way more than pretty much zero).

If a major manufacturer would make a quality 22LR, like a Buckmark or a MkIII, but it borrowed from the Phoenix Arms HP22A magazine design, I think it would be an instant hit.

Here's a picture of the HP22A 10-rd mag next to a 10-rd Ruger magazine:

You can see there's an indentation along the side of the magazine (on both sides) that holds the nose of the bullets in a single column. Then the base of the cartridges flare in either direction.

If the HP22A magazine were as long as a Ruger MkIII magazine, I think it might hold 16-18 rds.

Here are some more pics of the mags and the gun that shoots 'em.

This method works for 22 Colibris, which are even shorter than 22LR. So the challenges of working with a short, rimmed cartridge have already been overcome. It's just a matter of someone making the darn thing.

I Dont Know Why Kel Tec Didnt just make a Regular 22LR anyway. They had to pick the Magnum, Why not have the MAgnum option for an Upgrade.. I woulda bought that. And So would a lot of others, I would think... Anyway, My point is , I think they got that 30 rounder Bass Ackwords!!
