Got my gun back, they said they changed a couple of orings, raised the dwell & put the reg @ 130. passed shoot test.
Finally shot it & it showed between 260-270. the same thing. So i i uppped the hyper 3 to 135psi & my radarchron still showed between 260-270.
I have a .682 back, though i should be using a .679. But why no fps diff.
Maybe my radarchron is busted.
I just got my nt10/11 complete parts kit in & am gonna try te green flow insert with red tip. It came with a NT11 noid (red block) can i put it on my nt without any probs?
Anyway, the mystery continues.
