I have a 17hmr with a leupold fixed 6 power competition scope with target knobs. I decided I was going to have Trevor at Cloud Peak Gunworks Do a ballistic profile and cut me a turret. Well I got it back today (this is my first turret) and decided to go play. Well WOW TALK ABOUT PLUG AND PLAY!!! I went out set up a little 4x6 miece of metal then drove out Ranged back it was 231 yards and all I can say is i can not believe how accurate it is. range dial and shoot. there is not a prairie dog safe in a 250 yard radius if I have my 17 hmr. It is pretty sweet! I cant wait to do another one!
