Never figured that the 16 ga. was made for waterfowl shooting in the 30s. Yet I have a Western Arms Long Range SxS by Ithaca in 16 ga. with 30" barrels both marked 4. It has been a great duck gun with Kent Matrix over decoys, in fact is my go to SxS for ducks here. Was this a common choking in 16s for anything besides ducks in a hardware store shotgun?
