I use a RWS Scimitar in .22 with either a Bushmaster 3-9x40 on 3 mag and a lamp (Nite Hunter), or i'm just sorting out mounting my NV scope on it too.

The grip cocking and indexing lets you keep your eye on the target(s) while you reload, power can be dropped at the flick of a switch and it's incredibly accurate.

It seems to fire most decent pellets well, I normally use 20.5grn Penetrators on the rats but will give some of these new predators a spin next time (they fit if you load the mag carefully)

It's also indecently light.
