This may be something you guys might want to look into if you have a stash or even a box of Winchester M22 *Double powder charge*

And I've seen them at Canadian tire... I don't know why I've never grabbed a box..
How do they run through a Ruger 10/22, Walther p22, and Sig mosquito??? Thanks!
Yes, Winchester seems to be plagued with this problem. I recall back in the early 2000s there was a recall of Winchester 22 Wildcat due to this same issue.
Wonder if they can say "quality assurance"?
