I think it would be a shame to lose the .22 class, although i know where you're coming from.
It seems everyone thinks they can shoot better with a .177 these days.
I only picked up a .22 last september and have had a brilliant time with it, it's also improved my shooting with .177.
Perhaps the answer is to encourage it a bit more, instead of mocking so much.
Nearly everyone who shoots an airgun started with .22 and most still use one to hunt with.
John Mallows came up with a brilliant idea after the worlds, partly joking but still brilliant, that why not hold a competition that involves shooting all classes, like Triathlon.
Shooting .177, Springer and .22
Promote the lesser classes or lose them!
