My father uses them a LOT, and they are more powerfull than you think!!!!

I bought him a couple "hundred packs" for his birthday. Dad's been shooting pest around the farm with them for years!! I'd say he shoots 2 to 300 of them in a years time. Of course, he has one rifle sighted for them, and he has no problem killing unwanted pest around the house with one shot.
