Personally, I'm a fan of the Sako 85 chambered in .204 Ruger. It's the perfect gun for hunting prairie dogs. It's really the perfect use: you get to hone your skills and help farmers deal with their pest problem.
check me on youtube. call4deadproductions. I haven't made any videos yet, but in a while, I'ma have a video on a styrofoam & cardboard barret 50cal I'm making. It may not look perfect when I'm finished but it's good enough.
