Well, 4 inches high at 100 yards sounds just fine to me. That should make you on at 25 yards, and again at around, maybe, 350 yards?
Edit: Just reread your post...you said .17 HMR, and on my mind was the .17 Remington. Sorry about that. I can't recall the performance of a .17 HMR, off hand...I"ll have to do some digging.
