I've never shot an actual Browning A5, but last summer grandpa traded me a bucket of tomatoes for a Savage copy that he got as payment for auctioning an estate sale. Took it home and shot 5 clays off the back porch. The damned ported poly-choke liked to have deafened me, but I hit the clays.

On the poly-choke side of this debate, dad has one on his 20 guage 870 Wingmaster. I was probably 12 or 13 years old before I knew that shotguns came any other way. Hard telling how many quail he has killed with that gun. I would never add a polychoke to a new gun, but on that old 20 guage, it fits.
