Depending on your skill at shooting it a 30ftlb rifle will extend your range considerably, plus of course much more hitting power, ignore people that say it only gives you a few yards extra, either they cant get an FAC or they cant shoot usually

I have humanely despatched rabbits in excess of 100yds with one in the right conditions and that aint BS its fact although the Ripley I was using was over 30ftlb, 80yds will be no problem if its a calm day

Personally if I was to have one FAC PCP I would go for a MKI Rapid and have the hammer cap thread extended to allow power adjustment from 10 to 30ftlb so making it suitable for Feral pigeons around the farmyard etc

The s410 FAC rifle from AA has a power adjuster now too
