Try following through better after the shot. I am not as good past 30 yards either. It's more than likely got nothing to do with equipment. I think it's just a shooter problem. I for one would tell you to try a release, follow through until the arrow impacts, and then start thinking it's something else. I couldn't shoot serviceably at that range for some time. I felt perfectly confident at 30 but it's a whole different story at 40. You have to work on form more than anything in order to compensate for the extra flight time of the arrow. It took me months of practice butI finally disciplined myself for that range--andI don't even a have a 40 yard pin. I use regular 4 inch vanes off a WB.

I'm not the expert butI would have to guess it doesn't have anything to do with equipment. Too many people blame the bow or something when they should belooking intoform and shooting method. Accuracy takes time and effort. Don't expect it to be easy. That's my two cents of knowledge.
