Squirrels have been knawing on my "Ground Neutral" power line causing fluctuations in the current so I've decided to purchase a Smoothbore .22 Caliber rifle. Found a rifle (Not Inexpensive) and went looking for some ammo (I'm at a local gun show) and find three 50 round boxes @ $25.00 ea. Haven't bought any in a while or even seen any but that's HIGH PRICED Squirrel ammo, it may not be powerful enough unless I'm really close and the squirrels aren't "Sitting Still" targets either. Any experienced Rat Shot Squirrel shooters reading this?
