We went back out today and had one flock of about 25 set up on his perfectly.  I shot one goose with one shot from my NH of 1 3/8 Bismuth 2, Scott shot two with two shots of 1 3/8 Bismuth BB from his EH, and...........Bill shot one goose with 4 shots from his 3 1/2" NID.  His last shot dumped a small one at about 70 yards with 1 5/8 of Bismuth 2.  Not sure where the rest of his shots went 
Conditions were a temp of about 30 degrees with 30 mph gusts out of the West.
