I have witnessed .17 HMR's in the field and do not rate them in terms of accuracy, orthe fact that they appear to need a lot of cleaning after a relatively short period of use. They are also loud. I have a Anschutz target .22 lr, using PMC Moderators' at 950 fps. with a silencer on there is absolutely no noise and it does the business at 100m. I would not swap it for anything.
