A Speedy with Persuader/Gatekeeper and a Boomerang wrecked me today. Hurt my Nimbles hole! Don't know the Fun Facts sorry...
The Chaperone is really good at close range since against big body types all it's pellets will hit them since they are a big target and do a lot of damage. The auto fire and faster realod than the Persuader makes it a very aggresive gun so long as you keep moving. Inflatable Insoles are better for it since you can jump towards or over someones head and still keep firing at them aiming for the head while they try turn around.
