Full auto allows your shotgun to fire in fully automatic mode. In edition it is widely known that it also increases your fire rate. What most don’t know is by how much and that full auto has a third effect. From these tests I determined that it increases your rate of fire by 100% or 2 times faster. This affect will make all shotguns kill much quicker with 2 shots and although fast firing shotguns to kill incredibly quickly. As well it will although for awesome burst damage on difficult PVE targets. The third affect, and the one which was recently changed with the 2.4.0 update, is the increase in shot spread or lose of accuracy. This used to be about 40% causing you to lose a lot of range effectiveness. Now it is about 20% which makes it much less of a lose at range. This change makes shotguns something you'll want to look for on your shotgun. Do you like full auto on your shotguns? Which shotgun do you like it on?
