"hmm I thought you used rifles with scopes not shotguns to hunt deer? I'm not a hunter, just a handgun carrier, but it seems to me a shotgun is more for use on birds and small game like squirrel & rabbits, not big game animals like deer. A 30/30 would be a better choice of a deer hunting gun."
Some states mandate shotguns only for deer hunting, hence "buckshot" or slugs. Their thinking was that a shotgun's limited range would make the hunt more "sporting" and the massive trauma from a slug or multiple buckshot hits would be a more humane death for the deer.
Personally I have found a well placed shot with my 30-06 is quick and quite humane.
Also, most of those areas are fairly heavily wooded. A shotgun with a slug barel and decent sights or a low-power scope permits one-shot kills out to past 100 yards, generally as far as one can see clearly in the terrain. My dad took one whitetail with a 12 ga and a 4 power scope at 175 yards, standing, (while in his 60's), but dad is one of those guys who shot 'possibles' in the military with a rifle.
As for Kerry's picture, not many states ( if any?)permit deer hunting with dogs.
