Shooting prairie dogs all year long ,whenever the temp in over 40 degrees and the wind is under 15 MPH , is my sport.. The 17 rim fire rifles are used on prairie dog pups . The 221 Fireball and 204 Ruger are used on the survivors during the summer and fall. By late fall ,winter ,and untill the pups come out in the spring the 22-250 Rem, 220 Swift, and 243 Win is used for the longer range prairie dog shooting. I have used the 223 Rem but the 204 Ruger has about replaced it like the 17 rim fires has replaced my 22 rim fire rifles for prairie dog pup shooting. I,ll be getting a 17 Fireball to try out but I dont know if I ,ll get a Remington or some other brand rifle.
