Thread: 303 vs 12ga slugs

Id pick the 303.
Actual accuracy aside (id expect 303 to be much more accurate) the 12g will have a crazy amount of drop, severely limiting your distance, and making shots at different distances a bit of a crap shoot due to the rainbow arc of the projectile.
Also to keep in mind, is depending on where you are hunting, shotguns are not allowed on public land.
