Thanks, I was curious what it said. I've loaded up to 66.5 with the etips with no apparent high pressure signs. Wondering if it's worth going more or not.

Yeah, you could probably gain a "tich" more velocity by loading to 65K psi. But the increase in velocity would be minimal and you likely wouldn't gain enough to have been tickling the dragon's tail in that manner.
