Duffy you hit on one of the problems!!!!!
Yes at 25 yards you can take a deer with just about anything! One of the problems is that " Good Ole Joe." always sees deer at 25 yards, so he' s hunting with his trusty .22 CF, see' s a good deer at 2, 300 yards, so he flings a ' Hail Mary!" (#1 No discipline!) Deer trots off unscathed, Joe shrugs it off " I musta missed" , and goes home. Buck runs a mile, suffers a week, and dies, trophy ruined!!!! (Not to mention the reputation of Sportsmen everywhere ruined)!!!!!!!!
Just one of the possibilities! Still looking for ONE GOOD reason to use a .22!!!!!!
