After over 35 years of shooting a 12 ga., I'm getting tired of being beat up by the kick of a 12 ga. slug. My guns are old and I need a new shotgun for next year's deer season. I'm leaning toward a 20 ga, auto with a rifled barrel and a 4x scope(something like a Remington 1100). Does anyone have any opinions on the 20 ga. for use on N.Y. deer?
