I thinking of a new autoloader. I field hunt Canada geese.My previous gun was a 3.5",and it gave me troubles. Does a 3.5" really offer that much more? I've heard they don't pattern aswell as 3" guns. With all the new ammo I was thinking maybe a 3" is just as good. Now I know a close range,probably no diff. However for those birds that don't commit too the spread;ranges are a bit longer. What do you guys think?
