it is not legal in most states ; ( as it should not be).a 22 for turkey is sorta like a 22 for deer.illeagle and just not the right gun.
I have hunted squirrles with 22 rim. all my life,and only take head shots.you could do the same with the turkey ; (if the head would stay still long enough),thats the thing with turkys , they don't hold that head still for very long.
I think it is illeagle because it just is not ethical,even a head shot just 1/4"off and you have a wounded bird that will die out of site and be wasted.
JMHO;[&:]

in Fla. it is legal to hunt with a rifle as long as it is center fire.( the thing with turkey hunting ,is getting them in close).that way you don't need a rifle.
