Frankly....I don't give a "rip" about what my bullet is doing speedwise....as long as it goes where my "call" is...whether it be 200 yds. or 1000 yds.!! And if my hit registration coincides with my call  on the target face....that's all I need so in the final analysis.....it's a moot issue with me as far as spending time behind a chrono! The true TEST...is what comes up on the face of the target on a day to day basis!!

In the past I've attempted to use the chrony but with an OPW  and a "wad of bullet lube" going through the screens....well....the consistency was about as regular as my wife!!
