RE: Ammo of Choice?
I would pattern your load,choke, and gun combo to see what kind of patterns you are getting.
I've found that with steel loads, increased velocity has made a huge difference for me. I've had good results with Winchester loads that are 3" of 1 1/8oz of #2 (#4 first few weeks) at 1,550fps. Patterns have been very good and cripples have gone way down. I like the same load in 3 1/2"with BB's for geese and late season ducks.
