I'm considering a Browning Gold Hunter in 3.5" 12 guage, to use for ducks & geese. *Does anyone have any experience with this gun? *How about the 3.5" shell? *Is there any practical advantage over the 3" 12 guage? *I used to use a 10 guage for geese, but found the guns too slow and heavy. *The Browning 12 guage guns seem to handle very well in the gun shop, but I've never shot one.
