385gn arrow = 294/295fps thru chrono anytime.

This shows how chrono arent built the same,i have more draw weight lighter arrow and im getting 285fps.It's either the bows or chrono that isnt consistent.To many things come into play.

I don't think its the chrono's that make the difference here.

Would you explain yourself!!!!!!!!!!!!!!!!!!!!!!

Would you explain yourself!!!!!!!!!!!!!!!!!!!!!!

Bows vary in speed due to manufacturing quality or a lack of it, some are setup different as far as wheel rotation or tune. And some bows aren't exactly the same, different strings with lower strand count and lighter materials, etc.

So basically, 8.4 fps error.

The accuracy + or - can play its part but for someone to have each shot consistently at the extreme end is a bit much to pin on a accuracy error.

Maybe he uses wicked1 strings..........................................

I've shot my FC and most of my other bows thru my chrono and thru one at a shop 45 miles away and only get 2-3 fps difference.

Sonny, sorry I haven't got back sooner with answers to your questions.

1. The timing looks good
2. Using a QAD dropaway
3. Center shoot is good, shooting bullet holes through paper
4. Scale used to weigh arrows is the one I use to weigh all my arrow components
5. Yes the scale used to check DW is correct and to check we used a second scale.
6. Shot through chrono 6 times, 4 were duplicate and 2 were 2 fps faster at 254fps
7. Used a led light kit on chrono inside a garage with normal lighting.

One thing I have found is that the ATA is 32 7/8" and according to Martin website it should be 32 1/4"
also brace height is 6 3/4" and should be 7". Would this make a difference in the speed? Also I know just enough about bow tuning to be dangerous so what would I need to do to decrease the ATA and increase brace height.

In other words, you're right.

I like that, sounds nice Sonny......
