I am currently exploring to purchase a non Restricted semi auto 22 mag rifle. But it looks like most of 22 mag rifles I see in the market are designed as bolt action. Any idea of a particular brand or dealer, new or used who might carry a 22 mag in a semi? Any particular brand recommended for a semi?

cz 512

I have the semi Rem 597M in .22mag .
It will not cycle 45gr ammo and seems to over cycle with the higher velocity fodder.
Staying with 40gr ammo it's great.
If. I were to get another it would be the CZ 512
 
There's not many 22 mags semi autos around because its difficult to produce reliability in that cartridge. Not sure why, but I assume there's so much pressure in that hot 22 that a fine balance is needed between bolt resistance (static inertia) and safety... Obviously a few companies have taken a stab at it, but word on the street is that such rifles are not the most reliable. It would sure be a cool little rifle to have though if someone can do it right.

The problem with 22 mag in general seems to be around the short accuracy zone before it goes transonic, then accuracy degrades quickly. Inside that distance all is well.

I don't find a problem with that round, and my Anschutz bolt gun ,shoots them accurately.The problem with 22wmr semis, is the low quality guns that were produced for it.The Ruger 10-22 was terrible, and some blew up, and the gun had to be discontinued.I don't like the regular 10-22 either, as it is also low quality, that requires many aftermarket parts to make it shoot well..The Remington 597 was also unreliable,inaccurate, and low quality as well, unlike the decent rifles they used to make, before wall street bought them out..The CZ 512 is a great rifle and I have never heard any complaints about it, as it is properly made and shoots straight as well.As with any rim-fire, accuracy depends on ammo selection,decent optics, and a good quality firearm.

That's not the reason behind the accuracy shortcomings of the .22 magnum round.

The problem is that it, like the 17hmr, is not available as a match ammo. In short, these rounds are very much like high velocity .22LR ammo, none of which are made to the exacting specifications required for rimfire accuracy.
 
I'm surprised that you of all people would would make that argument.
I whole heartedly disagree.

I have watched supersonic bullets fly straight, then start daring about after about 75 yards. Shoots fine at 50, then goes to hell farther out. I have no reason to accept that its just badly made. Equally badly made cheap ammo does not suffer from the same characteristics. Sure crap accuracy and wide velocity spreads, but more linear results at increased distances.

You may be surprised simply because of a lack of information and perhaps because your eyes may not be seeing what you think they're seeing.

First, commonly used 40 and 30 grain 22 WMR rounds have MVs from between about 1875 and 2200 fps and the bullets maintain supersonic (greater than the speed of sound) velocities out to 150 yards and more. The transonic zone is from about 890 fps to about 1340 fps. The 22 WMR bullets in flight don't slow down into the transonic zone until they've gone past 100 yards. As a result, if transonic turbulence was responsible for 22 WMR accuracy shortcomings, it wouldn't be a factor until after the round is beyond 100 yards.

Second, with regard to the bullet behaviour you say you see, it seems impossible for anyone with the naked eye or with a rifle scope to watch or follow an 1800 fps or more bullet in flight and determine that they "fly straight, then start dar[t]ing about after about 75 yards."

Regardless whether you're aware of it or not, the fact remains that 22 WMR ammunition is not made to the specifications required for excellent accuracy. This is the primary cause of the relative inaccuracy of the average 22 WMR round compared to quality 22 LR match ammo. The 22 WMR ammo is designed as a hunting and plinking round and so too is 17 HMR and 22 LR high velocity ammo. They are not made to be especially accurate.
 
I have a HK 300 in the box with all the stuff
The problem with the gun was, it was to expensive for the average person at the time
The HK 270 shared the same problem, expensive to purchase and expensive accessories
I also have the 270 22lr,
