Here's my setup Tomkat 27" DL, 70lbs, 26" Goldtip XT's, TTSH fallaway rest. Here's my situation, (my bow has been tuned by the way), I was shooting 100grain field points and broadheads, I wasnt getting very good groups with my broadheads so I decided to try some different things (I'm shooting Muzzy's). I went to 125gr broadheads and noticed a difference, a good difference. My broadheads groups really improved. I sighted in with 125gr field points first and got my sights dead on with them, but when I changed to 125gr broadheads (muzzy's), my groups were on left to right, but they were approx. 3-4 lower than my field point groups. I made the adjustments on my sights for my broadheads and they group wonderful. My question is, on the easton tuning guide (if I followed it) it would suggest I lower my nocking point since my broadhead groups are lower than my field point groups Should I do this or should I just leave it the way it is? Any comments would help. Thanks.
