Battue,

Good stuff to think about there with the chokes and shot strings. I used to be an avid waterfowler and the go to was 3" #4 for wood ducks and teal early in the season and #2 for the big ducks later on in the season. All shot through a modified choke. Could be I was possibly doing something a bit wrong. Did pattern a 3 1/2" 10 gauge and a 3" 12 many years ago and you could tell a difference. Don't know about the shot strings but one noticeable difference back then was my success with the 10 was better. Bigger bore better patterns I don't know but interesting stuff to think about. Shooting over water you always knew who was shooting the big stuff. Still got that 10 gauge and won't get rid of it but lighter options exist now days and better shells available. Hope you have a good hunting season and the birds are plentiful!!
