If so, they should be ashamed.
I'm partly joking - partly serious. I love 22 centerfires as groundhog shooting was my main hunting interest for years and still would be if we still had groundhogs. But that's what the 22 centerfires excel at and should be limited to. Shooting a deer with such a cartridge is pushing the limits too far. You have to use the very best controlled expansion bullets and limit shots to broadside only and even then you barely have enough of everything to make a clean kill. In other words you have a rifle that should only be used by the most experienced hunters who are very good shots. But most of these guns are going to be used by inexperienced shooters because they are easier to shoot because of their light recoil.
I know they are legal in TN but I think it was an irresponsible decision that our lawmakers made when they took away the 24 caliber minimum for deer.
