RE: 00 buckshot for coyotes,deer,and bobcat
Well, yes more than a rifle, but then your state may restrict what you can use. If you pattern your shotgun and happen to have a still target on yote and bobcats, you may be able to pattern more towards the head. But that is iffy; my experience is that missiles the size of 00 Buckshot do not respond well to chokes. Groups pattern better out of a cylinder bore. That is why military and police shotguns are cylinder bore. I am sure you could use smaller buckshot on yotes and bobs.
