It "passed" as you say and as that was the chrono in use, thats all it got to do, though yes compared to the Skan i have borrowed here and the Tondu Chrono, to me yours is reading slightly high? I know others said they thaught it was low?
As far as i am aware, Mike williams uses this chrono to set up all his guns. I have borrowed it and think i will splash out the 190 for a new one. What i would then do is set my guns by it, but then re-cailibrate to the Bfta chrono. Being a must do job as an Njr owner, first thing i do at any shoot is check my gun on the chrono in use. Its a practise i see no reason to change?
mine go over bfta on the low side 790s if it groups or i start having to put clicks on i get the chrono out,some guns can be quite bad like 15 fps spread over a chrono but good grouping,dont get in a pickle with chronos matey,if you miss a target its the shooter not the gun
cr 97 in jim vickers ft stock bsa big 60 scope, and silly about of hunting guns
