When i put it through the chrony the first time my average was 309fps, this time around it was 312.

When i first got the string i put a VERY light coat of daltons on it...not enough to slow it down. I could be wrong, maybe shot some wax off & picked up 3fps

What i don't understand is from what i've read everyone is picking up a little speed or maintaining, i lost about 7fps to my viper-x. No deal breaker cause my scope is still dead on, just trying to figure it out.
