Need some advice I will be hunting teal and duck soon over decoys and in flight. I shoot a Cordoba so 3" is my limit, I am a bit confused with shot size ie BBB, BB vs 1,2,3,4, etc I am looking at the Kent's Fasteel, I was looking at Black Cloud but I have a ported barrel so that is a no-go)o; .... I am looking for a middle ground as I would like to purchase a case of 3" what shot oz. is recommended and what shot size should I use. Thanks for any advise.
