Also take a look at the 17 Fireball and 204 Ruger cartridges. I started shooting prairie dogs in 1949 with a 22 RF rifle. I live in p dog country and over the years have looked for the ideal p dog rifle and scopes. So far I have shot p dogs with 17 HM2,17 HMR, 17 Hornet, 17 Fireball, 17 Rem, 204 Ruger, 22 LR RF,22 WMR, 22 Hornet, 221 Fireball, 222 Rem, 223 Rem, 22-250 Rem, 220 Swift, 243 Win, and a few big game rifles. If I could have only two p dog rifles they would be the 17 HMR and 204 Ruger. The rifles would have Leupold 6-18X AO scopes on them. I have enjoyed p dog shooting with all the rifles. P dogs become muzzle blast smart so I use the 17 RF rifles when shooting p dog pups in the spring when they first come out. This year I have a new accurate CZ 527 Varmint 17 Hornet rifle which I ll be trying out to about 300 yards. I also like low recoil rifles.
