Re: Would a 20ga. cyl. bore semi be usefull for birds
At one time all shotguns were cylinder bore, then chokes came into play, or regulation as it is called in Briton and Europe. Chokes cause deformation of shot with older ammo that didn't have plastic cup shot wads. With todays modern ammo you are shooting at least one choke size tighter than what your choke is and a lot of people over choke themselves and handicap themselves. With modern ammo a cylinder bore will be just fine for grouse and any bird over pointing dogs. Again, long barrels were the result of black powder that burned slower than smokeless powder, with modern ammo 30 inch and longer barrels make no sense for hunting purposes..
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
