I have a high country carbon 4 runner (4-5 yrs old) It would only let me adjust draw length from 29" to 30". I ordered the next size cam for it, now it goes from 28" to 29". 28-1/2 is where I needed it.
I know some of the newer bows have a wider range of draw length.

Like mentioned above, maybe the peep sight wasn't adjusted after draw length was? What type of release do you use? Do you use a string loop?
I was able to shorten my string loop, that helped a little.

Just some of the things I ran into when I was messing with draw length.

Good luck!
