Well my .22 does pretty good up to 100 yards, so I guess I will be looking for longer range. Probably shooting squirrels, prairie dogs, and the like. This actually brings up a few more questions for me. For just destroying stuff below 100 yards (such as watermelons, potatoes, and other "explosive" fruits), would the .22 mag or .17HMR be better? Also, you said to stick with the .22 mag below 100 yards, why is that? And finally, would a .17 HMR or .22 mag have enough impact to kill a coyote with a head shot at 100 yards and above? From the videos I have seen of exploding prairie dogs, it seems like they would. Thanks again.
