Range report on the .17 HMR. We used the Marlin 917 (made a mistake earlier up-thread identifying it as the 817). Very similar to this gun.
You can find them on Gun Broker for under $200. The bullets are only slightly more expensive than .22, running around $12/50 rounds.
I love, love, love this gun. You have to try to miss with this. We got to the .17 after shooting about 50 rounds though my Mosin and my FIL's Springfield so we were already having that subconscious reaction to the big kick of those. Even with this, the shooting results from the .17 was great. This was 100 yards with a 7 power scope.
