I don't think Ruger ever produced it. I believe it went the way of the .17HMR. Remington did produce the .17 HMR auto for about 6 months then cancelled production and recalled all the rifles sold.

The problem with these guns was case slipping and blowing out if not kept clean.

But here are some other choices.

I had h and r one long time ago, the bullet dropped fast after 130 yds, I got 10 shot clips and they sometimes failed to load next bullet

Ruger made a few but pulled them fairly quickly as magnum has a strange pressure curve for a blowback action.

Yep.The casing slipped back some before it locked onto the walls of the chamber.Some of the casing would be hanging out and when fired it blew out. Just so everybody understands.

Keeping them really clean helped but the big manufacturer's were not going to have the liability of it.

I checked out the Savage A22 it has the rotary clip I guess it’s on my bucket list now!

Have you seen the Ruger PCC carbine , it is in 9mm right now but there is talk that there will be a 22TCM barrel made for it

That could get interesting

if you don't know what 22TCM is it is an Armscorp invention to put a high velocity 22 in a handgun the case looks like a necked down 9mm it is really a 223 case cut down then necked to give it greater web strength it gets 22mag rifle velocity with a 5 inch barrel and 45gr round nose .224 bullet about 2050 fps , in a rifle it can get 2750fps.

By the way, I do own the Ruger 10/.22 Magnum but that was made a long time ago....just don't see any new ones offered.

I don't think Ruger has one.Voquartzen would be the best but very expensive.Magnum Research has a decent one,cheaper than Volquartzen but not cheap.The CZ 512 might be worth looking at.It is said to be very reliable.

Vermontster,

The .22 mag is more than enough for Coyotes. It works well on most everything up here from Fox to Wolves. I like the 40 grain soft points with a metal jacket up to the lead. I put one into a Wolverine last year, down and out in about 3 seconds.

Its not a Semi auto , but I run a Savage 93 Heavy barrel. The clip could use improvement, but it Drives tacks and has a good Trigger. Mines chambered in 17 Hmr, but they also make the 22 Mag. My buddy has the A17 semi auto savage and Likes it so far I believe.

If money is not a issue. H&k 300 is the way to go in a auto magnum. Very pricey.

Superwide, I have been thinking of buying a Keltec CMR 30, but was curious how reliable it is running it dry. Saw your post on here, wondering what your experiences have been with it. Don't see wolves too often, my .223 is too big for lynx and fox, the CMR 30 looks like a handy rifle on a snow machine.

Winner winner chicken dinner-hands down the best 22 mag semi auto out there!! I have owned/own them all.HK 300 chucks the brass like 100 ft!! and it out shoots them all-bar none!! Worth every penny!!

ruger quit making the 22mag in 10/22 becasue poeple where barreling the action in .17hmr and blowing bolts up in thier faces. and for leagal reasons sold there stuff to magnum research. As magnum research still uses the action in there line up.

I have a magnum research 22 mag that shoots clover leafs at 100 yards with hornady 30 grain vmax. Very light rifle but the trigger isn't the best. Keep it clean and it functions perfectly

I have a Ruger 10/22 WMR that may or may not be on the market for a lot less than Gunbroker prices. Never had any issues with it, whacking 13 stripe ground squirrels at 100 yds with 40 gr. Winchester HP.

I have the Reminington .17 HMR auto and have had it blowback on me once. The clip blew out of the bottom of the gun and was ruined. I now keep it super clean and have not had it happen sense.It is a gun that was recalled but i kept it.

X2 their magazines are garbage

I have a Remington 597 and it has been fine but as mentioned I only put 5 in magazine. It has shot any ammo I've tried so far. I have a CZ 512 and it shoots great. Absolutely no issues with it. I also have an AMT with a heavy stainless barrel. It wasn't very good when I got it. But after a lot of tuning and trigger work it really shoots well. It's heavy though so I don't take it out calling much anymore.

CZ 512 good gun.
