Dead on for my envy... 333!

333 wow! At my DL (27") it will take Kevin at least 2-3 more years to hit that.

It just takes a little fine tunning and no problem. I got a little more than that out of it, but it tunned very well at 333.

60# exactly on a digital scale
29.25" DL
300.1 grain arrow

Dude that is an awesome speed, but I didn't realize your were horizontally challenged.

You should see me straddle a 250

[Michael]

Are you vertically challenged too? I have a CRF50 you can ride.

I am assuming that this doesn't really work for bows like the Fire where the IBO rating given is for 28" draw at 60 lbs. Is my assumption correct?

You can do it...the way I figured it out was the fire at 28inches and 60lbs is 1 fps faster than the synergy xtreme at the same specs. So I just put in 340 which is IBO for extreme and it same out the same specs. as Kevin sent for the bow. I also always include 12 grains on the string...I only use a meta peep and d-loop, but that has always put me dead on with a chrono...

i have 06 eforce at 27.5 draw 60lb, have the speed nocks on string ,sims string leaches 2 and kisser, and eliminator button, what would total weight be on the string? how much speed would i be losing? does it matter if you have string leaches on the cables? thanks , only getting 270 right now, with 325 total arrow weight

Its off for me with my Envy. Its telling me I should be 10fps faster...

Do you have the updated mods (they are black)? If not you will be about 10 off.
