To me when calling them in to 25 yards or less and they gobble.They seem to be a lot larger than whatever I am carrying.
I have a buddy that shot 2 gobblers with 1 shot out of a Winchester 97 pump at 20 yards.
It took him a minute to get his senses back after the shot,I don't know where he went but he was gone.He was using 23/4 no.5 shot. Full choke.
