I see this topic on several sites every year . It usually starts "I don't want to start anything , but ......" and ends up in a heated discussion .
I use a 22 for woodchucks and fox . I would never consider using it for deer and I don't care if
someone's cousin's brother's father-in-laws uncle shot a bunch of deer with a 22 .
If someone can't handle the mild recoil of a 243 , 25-06 , 270 , etc then go ahead and use a 22 .....
