I'd agree the everything Dustin said.

Being from GA you will likely be using it on woodies, maybe a few early teal, and possibly gadwall as they have become more prevalent here over the last 10 years. I will be doing a bit of experimenting on woodies myself with a 20 this year. I don't recall ever using a 20 for ducks, but I bought 14 boxes of 20 ga. NiceShot and bismuth a few months ago from a friend, with the intent of trying my Parker 20 on them. I have no intention of ever using steel loads with a 20 for ducks.
