Looking for some advice on the selection of a mid range varmint rifle primaraly used for prairie dogs. I would like this rifle to have low recoil so that I could see the hits and misses but have the punch and wind resistance to get out to 500 yards on a typical South Dakota day, windy ). I am set up well for the shorter ranges out to 350 yards and want to explore the next step in prairie dog shooting. I would prefer a factory rifle but would consider a custom if that is what it takes. Any advice on rifle make, model, caliber, bullet weight, and scope combination would be of great help. Obviously accuracy is very important. Thanks
