Does anyone have any documentation or a link to an RCMP notice banning the 25-round mags? I've haven't seen or read any confirmation myself; just comments here on CGN.
Found it:

It's just the magazines made by Ruger; they are a prohibited device unless limited to 10rnd capacity. Butler Creek, Archangel, etc. all seem uneffected.
Apparently Prophet River put out a bulletin that all 10/22 mags over 10rnds are prohibited now. Not sure where this is coming from. It was quoted on another site, not directly from them, so maybe just unfounded rumours
Loads of sites still selling 25-100rnd mags made by companies other than Ruger.
There was another thread a little while ago saying the Archangel/Promag 9-22 mags were also banned but I can't find anything to support that.
