My HMR has effectively killed groundhogs at 175 yards with a one shot kill to the head. It does an amazing job and the awesome part is that in it's effective range, it drops minimally. Prior to the 17 I had a little Marlin bolt action 22 mag. The round did well, but in all honesty I never pushed it past 100 yards for accuracy reasons. I was always afraid that the shot wouldn't be an effective kill. With the 17, I don't have that worries and I am comfortable enough to take a shot at 200 out of it if I were to need to.
