Slug and Clean shots are instant casts when you have a proc in gauss barrel. That's nothing but a straight up dps gain. You also get gauss shot and ricochet, a 200 and 400 potency respectively.

Split Shot, Hot Shot, Lead Shot = 3. Ricochet is 100 potency unless there's a secondary target to hit. Rapid Fire is a dps increase without gauss barrel and is only a mobility increase with gauss barrel.
