For the sake of accuracy, I'm saying I want to see the 17wsm necked up for a 22 and commercially produced with a semi auto platform. A 22wsm if you will. I'm not saying that there currently is a 22wsm.
....I got that, but perhaps I could have worded my reply better!
As a matter of interest do you know the actual size of the parent cartridge case, would it take a .22 or even .25?
Apparently it's out of a 27 cal nail gun blank, so I guess so. I really haven't given this that much thought tbh, lol.
