Most all of my shooting is at prairie dogs. Prairie dogs gets muzzle blast smart so I like the 17 HM2, 17 HMR, 17 Hornet ,17 Fireball, 17 Remington ,and 204 Ruger. cartridge varmint rifles. I like the low recoil of the 17 and 20 caliber rifles that lets me see the hits thru the scope. I have 22 LR , 22 WMR, 22 Hornet, 221 Fireball, 222 Rem, 223 Rem, 22-250 Rem, and 220 Swift rifles but don't use them very much for p dog shooting since getting the sub 22 caliber rifles.
