plain silly to choose to use buckshot over a slug. Throwing a spray of pellets with a limited range versus a precision projectile with easily 3 times the range.
Guys can talk all they want about the deer they have killed with buckshot, the situations it's good for but plain and simple it's because they worry about missing with a slug and think throwing a spray of pellets will give them a better chance. In other words they aren't confident in thier shooting and don't worry about wounding deer.
Buckshot is a 50 yd ammo. If you can't hit the deer with precision at 50 yds with a slug stay out of the bush.
My opinion and I am guessing that some State lawmakers agree whihc is why it's illegal in some places.
