Handcannon -12 rounds clip -Rangefinder -Perfect Balance -Exotic Perk- Your bullet pierces your target, then split into 12 projectiles (buckshot) and deal shotgun damage at anyone close behind your original target. A heardshot kill of the original bullet would make it bounce between three other targets (buckshot would be disabled from the bouncing bullet) increasing in damage from each bounce. But that's just dreaming, tho, we will never see something interesting like that in Destiny so i'll leave it for Borderlands 3.
