I know it's a starting point, and good for you... but 45-50# is not a warbow. It is, however, a great place to start. As mentioned, you don't shoot a warbow like a target bow... well, not for very long anyway. My advice? Forget the close range target, and go out to a field and flight shoot with it. Practice shooting in the bow, setting your bow arm height for max distance, and come to full draw (at least 30"). As stated with the EWBS, I think a minimum for warbow classification is 70#@30".
