X-finder...Welcome to HPA, we got a Tornado last year, and plan to get another Parker crossbow this year to further arm my troops and get more out there.
My 12 year old son and I both dropped does (his was a button buck actually) last year with ours set-up by Arrowhead. So it fits a wide range of hunters nicely without adjustment. They went 15-20 paces post-shot and they were both down for the count, exactly what I wanted in accuracy for us, both shots were under 20 yards out of a ladder stand.
My one tip, practice out to 45, but keep it under 35 when it comes time to take a life. You will love that crossbow, I did a big writeup on shooting ours in for the first time last year... I found it will drop a about an inch a yard after 20 or so.
Did you get the Hawke multi-recticle ?? If so increment it at 10 yards (we did 15, 25,35,45) and you should be shooting it great in no time.
See ya in the success forums in October. Best of luck with the new weapon.
