.17HMR...What are its capabilities?
I've consistently killed groundhogs at 200 yards with mine, the key is hitting them in the head region. Which in calm settings the .17 has no problem doing.
The longest shot I ever took was on a crow at 225 yards. It knocked him right down. The .17 is more than capable of 200 yards, but shot placement is more important than if you were using a .308.
