Can someone explain this? D. Holliday

I had my Hoyt Trykon re tuned a couple weeks ago. I've been shooting bullet holes through paper, and field points are right on when shooting at target spots at 20, 30, 40. Never been shooting this good. I bought some NAP Razor Caps 100 and suddenly my groups are sporadic. Some shots hit the mark, but most were 2-3 inches low or left. I was under the impression that if my bow was timed and tunned correctly I wouldn't have to change my sights for a fixed blade broad head. Is this a misconception, do you always have to tweek you sights for a broadhead. I've always used mechanicals so I've never had this problem, but was looking for a little extra penetration power. Thanks for you help.

sounds like plaining.

Maydar,

Don't tweek your sights. You need to adjust your rest.

I made that mistake last year before Kelly Johnson set me straight. Use the link to that thread below. It should answer your question.

Once you get the BH and FT grouping together then adjust your sight for POI.

Move your rest in very very very small increments to the right until they impact the same. If they keep impacting low then move your rest up up in very very small imcrements until it impacts the same. Then you're good to go. If you're not getting any better, then take a turn out of each limb bolt and give it a go. If it gets better then good...if it gets worse then put an extra turn in. Broadheads really show a missmatch in spine.

That is why I shoot the Snyper!

I guess I don't understand. Why wouldn't your fieldpoints go higher if you raise the rest, or go right if you move the rest right. Why would the broadheads and the fieldpoints end up having the same point of impact.

Most likely because paper tuning didnt reveal the that the bow was slightly out of tune. Paper tuning is a great starting place, but shouldn't be considered the final word as far as tuning goes.

Yes, your field points will also move a little bit...but the broadheads should move three times as much with each movement. Usually fixed blade broadheads will show a missmatch in spine for arrow/weight matchup.
