Some cans, like the Thompson Machine Zepher XL are rated for the magnums. But many, like my Gemtech OBII are not. I doubt they'd explode on the first round, but it's probably not a good idea either.
Of course, my OBII isn't rated for full auto either but.......
just get a Huntertown Arms Guardian 22!
its rated for .17 HMR, .22 MAG, and .22 LR full-auto
and at MSRP of $235.00 it won't break the bank.
NO on the .223 though as well...
