A Simple question on 3 sniper rifles

@TrancyGoose Kraber can one shot anyone that isn't Caustic or Gibby regardless of their armour levels of it's a headshot, even a body shot does like 150 or something which is more then enough to mop up with a secondary, but I can't land a single * shot with the damn thing even if the enemies are standing still. G7 is solid in mid range but fails in close quarters and long range. Longbow is definitely the best all-rounder since you can quickscope using iron sights and use a 4-6x or something for mid to long range, and because of the fire rate you can spam bullets like a * and pretend the random headshot you got was totally planned
