For now I'm using my waterfowling SBEII with an Indian Creek choke. These were done in the middle of jan when it was -4* out. It's a little tighter in the spring and I actually get the best patterns with the 3.5" 1.75oz in either 4, 5, or 6's. Never patterned anything else because thats the only three shot sizes we are legally aloud to use.
I have dialed her in pretty good and have been using open sights the whole time. I finally decided to pattern it at 20 yards (which is where I shot most of my birds) The pattern was just over 4" wide!!! Seeing that made me realized my 8-0 has been lucky and I need to add a scope. I have the base from weaver on order and now just deciding on a scope. Also thinking about adding a pistol grip stock.
