Either weather or trying the geography-Canadian geese are in NM-AL.
Using a 1923 AH Fox HE Super Fox 3IN double, got my share of large Canada geese this past week. Finding tungsten or right sized bismuth
shot shells harder than locating the geese. With a double -you can load different load in each barrel depending on the range.
BB or BBB seem to be the best bet, while B shot will work. Stubble and grass or corn fields work. They tend to go to large lakes to rest or
spend the night for security from predators. In NM-its alfalfa fields and irrigation ditch blinds. Same lake set up with competition from
snow geese and sand hill cranes.
