No way.
The .22m has a long and troubled history of working in semi auto weapons.
Too long and thin to feed/extract reliably, just look at all the failed concepts, even the Ruger 10-22 magnum was problematic.
Now a 17HMR might be interesting...
I assume most 15-22 owners would not buy a 22mag version because it would defeat the reasons they bought the 15-22. cheap training rifle, cure the "bug", cheap plinker, etc...
I either shoot "cheap" or "big". The 22WM would be neither, I'm afraid. I liked it when I had a Ruger single action with both 22 and 22mag cylinders, but not for a single gun. For me, at least.
Thanks for the info....don't see how I could have missed that thread???
Just been thinking about the Kel-tec PMR30 & the RMR-30 as I have a "thing" for same caliber ammo between pistol's and riffles...even better if they take the same mags...
Yea, was on my mind but as stated, to many issues with the case in a semi-auto. I just like the bullet, I got two other bolt rifle in 22 WMR and love them (Marlen 782s, one is Desert the other is black). Now the .17HMR would be interesting....
The issue I'd have with a M&P15-22 in .22 magnum is gonna be the ammo cost! I have an Ithaca lever gun in .22 magnum and I cringe every time I pick up ammo for that rifle.
I would buy 22 mag , who cares about cost of ammo . Plink with 22 lr , hunt with 22 mag . Another reason to buy another gun . If you want 17 hmr Alexanderarms in Radford Va. makes one.
