I have shot critters on our farm for a couple of years with a well beaten .22 Benjamin Discovery...but wanted to up grade. I bought a Benjamin Marauder Field and Target in .22 .
Critters have been eliminated MUCH easier and the rifle is a silent repeater. MUCH better. With a 10 shot clip I have doubled on raiding Raccoons and it's a VERY accurate air rifle out to about 60 yards...which is my Max range for critter elimination. At 50 meters it shoots a half inch group.
I put a 6.5x20 Leupold scope on it and a bipod to match the weight of my BPCR gun and we can practice in the yard with it.
