Hi,i'm a new member and need help in choosing an air rifle.Basically i need a powerful weapon for vermin control at my allotment.It's riddled with rats.Max distance i would be shooting would be 25m.It has to be light,easy to use,be able to have a scope and silencer fitted and of course be cheap as it will be only for vermin control.Ive looked in the mags and quite like the look of the Crosman ratcather/king ratcatcher however they get mixed reviews.Can anyone help/advise,point me in the right direction??Much appreciated,Richy
