hi all
how many rounds do you have to put through the chrono before you can get a reliable SD.
i did 3 bullets today,then it through it down with rain.
so i packed up.and i am out tomorrow if there is no rain.
on the 3 i put through my 243 AI shooting 95g VLD with 49.6g of n165.i got this reading.
pact chrono xp
high 3273.2 fps
low 3270.6 fps
SD 1.3 fps
CV 0.0%
mad 0.9 fps
CV 0.0%
av 3271.9 fps
es 2.6 fps
shot 1 3273.2 fps
shot 2 3270.6 fps
shot 3 3271.9 fps
and then like i say i had to run for cover.
so i am wondering how many should i load to get a good useful read out
thanks for all your continued help
