if your intention is to use buckshot, get an Ithaca road blocker shotgun,
or similar 10 ga, that throws (18) 000 buck with every shot.
thats double the average 12 ga shot guns 2 3/4" shell load of 8-9 pellets,
doubling your potential for hitting the vitals
and yeah, try hard to limit the shots to about 35 yards max.
