Hello all, I have been shooting a Bowtech Realm since last winter and love it. However, I began realizing lately that at further distances I was shooting low, and upon going to my local pro shop I realized that my bow, which was originally set to 70lb draw while shooting 475 grain arrows at around 265 fps, was currently drawing 65lbs and shooting 250fps. I was very surprised with such a large drop in performance in only 11 months with the bow. The individual helping me out turned my strings and got the bow up to a 69lb draw shooting 260 fps. However I am still skeptical of the current strings on the bow. Should I go back every so often to test it out, and are their other strings I can get where I will not need to worry about this problem? Thoughts? Thank you in advance.
