I have a Henry varment express........awesome rifle! Never leave home in the ranch truck without it! .17 HMR is a fast hard hitting round safe around livestock because it comes apart and a richoet is not as common in the 17 as it is in a 22 Lr or 22 mag. Down side is wind messes with the 17 and it wont punch through the grass or brush like a 22mag or 22Lr.....the speed and the safe factor of the 17 out weighs the lack of a heavy bullet in my application!
