Canadian Tire, Basspro, Cabelas in my area. A long way from you though.
I can find them at crappy tire at times but I'm looking for case. Used a box of the 3" 1 1/4oz #2 last year cause I needed shells real quick and that's all they had... Damn do they ever fold the birds up with authority!
4 steel is way underrated. Most ducks are shot at or under 35 yards, many have forgotten that pattern kills not power...
Kent has always been spotty to find for me, once I get my hands of it I always stockpile. The made excellent target loads as well, haven’t seen any in years
The GF and I shoot Kent 3" 7/8oz of 2's through our 20's for waterfowl. It kills birds cleanly.
