Twangy as Feck mate and not really much that you can do if your on about tricking one up.
Perfectly capable of taking out Rabbits, Rats, Squirrels and most of the Feather species with practice.
Ok as a fun gun or for a carry round when doing a bit of squirrel bashing in the woods due to the light weight of the thing, but don't expect much in the way of long range shooting.
