if i had that much land to shoot over my FAC would be sent of by now and a RWS 500 .22 set at 30 - 40ft/lb would be on order
but why fix something that isn't broke
your trusty .177 will do the job you need it to nicely.
at least that way you won't have to get used to a new/second hand rifle scope set up.
IMHO you'll fair better with something that your accustom to shooting even if it is in the girlie cal
