    Hello, all...

    I'm wondering if anyone makes a semi-auto .22WMR like the 10/22 that accepts high-capacity .22WMR mags. I'm kind of assuming you get an AR-style rifle chambered in .22WMR, but that's not what interests me.

    I'd also be interested in knowing the same thing about .17HMR or .22HORNET, if they exist.

    Thanks!

    Ruger made a 10/22 magnum for a few years. You might be able to find one used.

    I think the H&K 300 might still be available, but magazines are very expensive.

    I have never heard of a .22 WMR conversion kit for an AR-15.

    Semi-auto .22 WMRs are pretty rare. I have never seen a semi-auto Hornet.

    The .17HMR was tried in semi-autos and was a failure. The cartridge will not feed. I know not becasue I'm a guru, but because I just asked the same question last summer.

    CZ makes a .22 WMR semi-auto.

    Magnum Research and Volquartsen offer 10/22 replicas in .22Mag and both are well reputed. There are some 22-25rd magazines available for those. The Shooter's Ridge and ProMag magazines are cheap and unreliable. The Volquartsen version is over $100. CZ also has an autoloader. Alexander Arms has a .17HMR upper but only 10rd magazines. I've heard some chatter about a .22Mag upper from CMMG but so far nothing has surfaced. Closest you can get is a 5.7 upper for the AR which uses the PS90 50rd magazines. Yields higher velocities with a better bullet but costs quite a bit more.

    Also guns from Excel Arms, the aforementioned HK 300 and the old H&R 700 as well as the AMT replica of same. No high capacity mags for any of them.

    Wow, I am still in shock from the price on those volquartsens. :what: I think I will just stick with my Henry 22 mag rifle. All though if there ever was a severe price drop on those Volquartsens I think I would get one.

    P.S. not sure how true this is but I heard rumors that Kel-Tec was going to produce a 22 mag semi auto rifle similar to their pistol.

    They are. I've seen images of it and I think it was at SHOT. It's a bit odd and kind of tacticool looking, but so are most of KT's rifles.

    Marlin used to make a good one: the 922M. You might still find some on the used market.

    EDIT TO ADD: Sorry, forgot the part about the high-caps. I don't think there ever were any high-caps available for the 922M.

    The 17 HMR was indeed a failure in semiautos, but it feeds just fine. The problem is that the pressure curve is a bit too large for a production blowback action and it had a nasty habit of opening the action before the bullet had left the muzzle. This caused the case to rupture, often destroyed the magazie and showering brass bits and hot gasses everywhere .

    We need to clear up a misconception or two. The Remington .17HMR was a failure. In my opinion, a much overblown one due to litigious concerns. Volquartsen has never stopped making .17HMR rifles. To my knowledge, Remington is the only one that was and stopped.

    Natman is correct about the pressure curve, feeding is not a problem. If anything, the .17 would feed better than any of the .22 rimfires.

    There's a reason the Volquartsen's are expensive because they are very well made and custom bolt action accurate. I own 2 in WMR and one in 22LR and have killed hundreds of Nutria and Ground Hogs with them. When Ruger first came out with their 22mag I bought one but it fell apart after 600rds and they would not fix it and I don't think they make them anymore. Get the Volquartsen and it will last 2 lifetimes.

    Excel Arms makes the Accelerator rifle in 22WMR, only a 9 round mag though. If it performs like the Accelerator pistol, I can't recommend it.

    They also make something called the X-series with an available 25 round mag. One part of their site mentions a 22WMR version, but I couldn't find detailed specs on it so maybe it was recently discontinued? They do offer it in 5.7x28 which might be interesting.

    The RMR-30 looks like an interesting concept with a 30 round magazine. I agree that the Volquartsen would be a good purchase as well but pricey.

    Remington made the 597 (maybe still does?) in 22WMR.

    I've also heard that there may be extended magazines in the works, on the order of 50 or 60 rounds.

    I have a PMR-30, would love to have the companion rifle.

    I don't know if I would. They're pretty short already, and the .22 WMR really does benefit from the longer barrel

    Magnum Research also tried 17HMR semis. They even drilled a tiny hole in the barrel to bleed off some pressure at the peak, a mechanical kludge if ever there was one. It still wasn't enough and they stopped making them too. Ruger wouldn't touch it.

    I suspect that Volquartsen charges enough that they can afford to test and fine tune each individual rifle to make sure that the spring strength is just right.

    I don't know about the 17 HMR KABOOM problem being "overblown". It seems to me that having your rifles explode is a problem worthy of some serious concern. We sold three 17HMR 597s in the shop, two of them KABOOMed, one on the third shot. Remington replaced the two with rifles in other chamberings and the third guy had his rebarreled to 22 mag.

    To my knowledge, Remington still makes the mod597 in .22wrm.

    When you said "high capacity" magazines, you essentially eliminated all .22wrm semi-autos. My Remington M597 has been an excellent rifle. Yes, the magazines are plastic, but mine with the exception of the Federal 50gr "Hydroshok" load, functions perfectly-all three of the magazines.
    With "good" ammo, it approaches MOA at 100yds and has taken a tractor-trailer load of game/varmints to include several deer.
    Mines a "keeper"....
    Good ammo includes the original Winchester 40gr JHP and FMJ ammo. The Remington and Hornady 33-35gr V-max ammo is superbe, and the Federal 50gr Hydroshok was very good till discontinued. I just couldn't load but 5 in the magazine. If I loaded 6 or 7, they would "nose-dive" and hang up on the feed ramp of the reciever.
    My rifle came in the "plastic" stock. I bought a "blem" from Boyds and fitted it and glass bedded it. The rifle is now rock stable and only changes POI due to changes in ammo.

    If you can find one, I can recommend the Remington M597.

    I heard the 22mag auto is subject to extraction issues, but have no experience so ignore this post :neener:

    I couldn't really find any, which is why I made the post. I was simply intrigued by the idea of a "10/22 Magnum." Interestingly, I never knew that there literally was a 10/22 Magnum. LOL... They're going for almost a grand on Gun Broker. There are lots of things I'd rather have for $1,000 than an old 10/22 Magnum that seems to have had issues.
