Predators...what your favorite buckshot?

[unclebuckpa]

Here in Pa we can only use up to # 4 buckshot for predators. What's your favorite buckshot for predator hunting? I know you can use 00 if you desire in Va... Just wonder how well they works or are many of you like Pa predator hunters and prefer the # 4 buckshot for coyotes, bobcat, and or fox?
