Mossberg 835 ulti mag waterfowl shot gun
I have three barrels for mine, including a rifled one and the others have chokes you can change.
I've used #4 buckshot, 'T' shot' and some of the 'Hevi-Shot' 'waterfowl' loads in the larger shot. For most of the coyote hunting I have done, a shotgun makes more sense than a rifle. The action is close range in thicker cover.
