Have had an R9 in .177 for about 8 years now.
Have shot game/pests from 10-50 yards.
Have shot targets from 10-100 yards. (yes 100, hope you have a backdrop that kick up dust, a spotter and very low expectations)
Excellent rifle, very accurate with power to dispatch pests. Routinely shoot feral cats and coons DRT.
Also eat a healthy amount of rabbits and squirrels. Rabbits are easy to kill, squirrels are more muscular so keep it within 40ish yards to ensure a headshot.
Would buy again in a heartbeat, awesome rifle.
