I don't doubt the capabilities of the 22s on deer. I've seen a 223 used on them before, even with light little bullets things die. Eventually. The 22-250s are much nicer, and when I get a high-power 22, I'm planning on a 22-250 (yes, I plan on getting one for varmints/targets and just plain fun). But heck, I need at least a 6.5mm to be legal for elk in NE if I get the chance and want to use my [now] pretend rifle. I like 6.5s, but there's nothing wrong with the 7mm if that's what you're gettin at .
