Having problems getting broadheads to tune. Shooting Drenalin at 73 lbs. draw. 28.5 inch carbon express 300 arrows with 125 grain points/broadheads.
When I started shooting BH's they were 5 inches low and 4 inches to the left of field points. I first lowered nocking point which brought the BH up to same level as FP. Than I moved the rest in (to the right). After several adjustments it is still 2-3 inches to the left of FP's. I am now to the right of center with the rest and at the limit for clearance issues. Anything else I can try? I also just bought some Maxima 350's and tried them. They are shooting close to the same as the 300's. By the charts the 300's or the 350's should be fine for proper spine. Last season the guy at the "Pro shop" " paper tuned it for me. He had the nock point set 3/4 inch high and the rest was a good 5/16 to the left of center. At that time it was shooting the BH's and FP's wonderfully. I had new bucknasty strings put on recently and the alignment marks on the cam line up. The nock point is now 1/4 high and the rest is about 3/16 to the right of center. BTW arrows have 2 inch blazer vanes. I will start over with walk back tuning (again) and check closer for clearance. Any insights or helpful hints appreciated, Dabow
