I belive some of the 22mag's rep concerning innacuracy comes from the inconsistancy of the ammo. It is Not created equal. CCI now loads for Rem 22wmr because Rem's production was - inconsistant. Winchester 22wmr production is moving - or has moved but I'm unsure of where the new lots of ammo are at this time. Stuff like that. Armscor's still smell like egg farts once fired. Winchester makes the supreme - top shelf, and the dynaturd, ( a sort of acne copper wash meets a deformed chunk of lead ), a low end rubbish round.
So I generaly stick to what works and zero in.
Some people complain the 22wmr is expensive for what it is compared to the 22lr. yes it is, as is the 17hmr's cost is about the same yet the 'craze' is there. I don't buy comapring lr. to 17 or mag round, the make up is a completely different animal.
I don't consider the mag an over 100 yard tool, if I had the time to zap evil crows I'd consider the 17's extended range. The mag, however in either flavor had a lower report that is appealing. I don't expect shooters in everypart of the globe to understand that the way many shooters / hunters in a more densely populated area deal with. Almost any rimfire is a great tool to teach youngsters. And if your on a budget the mag also makes sence. I shoot a 25mn, that has a tweeked triggor advantage. And decent glass. I typicaly use a fmj-sp for light game and the 40-hp on critters. Although if the Marlin could talk it will say tons of possum fell to the supreeme, and that would be correct.
