I have been haveing a time trying to get my arrows to fly consistantley at 50 yards. I am useing a platinum premier rest and a conquest pro by Mathews. The arrows I have been tring are the goldtip 3d pro.3555 at 28" with a 80 grn tip 3" fletch. I have tried every thing. I started with the arrow set pefectley to the string and perfecley level to the knocking point. I have paper shot it and adjusted the paper tere to be slightly high1/4 to 1/2 inch. This is what I read in tuning and shooting your 3-d bow by Larry Wise. I have even tried different weighted feild points with no avail. I have even adjusted the rest from left to right and back again to see if this would help the groups. I have changed my set up because I have been drawing at 70lbs and wanted to try to back off a little and go to a lighter arrow. the set up I had worked fine and I got good groups with it. Im talking grape fruit size groups at fifty( I know thats not as good as you guys shoot but good enough for me). The problem is Im no a kid any more and get tired pulling 70 lbs after 40 or so rounds. should I go with a different arrow ? or should I try adjusting the weight till the groups come back ? I am pulling around 60 to 65 pounds now. any suggestions are appriciated thanks again for your help. PS if you have a suggestion on a good arrow set up that will work with what I am trying to do I would appriciate that too. THANKS A LOT!
