Fired out of my Ruger Blackhawk at 1000fps, these pellets fly very accurately and hit hard, due to their flat head. Consequently, they don't penetrate very far, but they have great knockdown power. I used them mainly for target practice, and they made large water bottles explode at long range.I would recommend them for target practice, plinking, and I have no doubt that they would do a number on pests from rats to rabbits.
