Thread: CDS/Chrono Question

Good on you presenting the barrel cleaning history before that session. Question is how consistent you can ever be in future ?

Predicting a velocity increase between cleanings is a rabbit hole. And you need a lot more than 3 shots . See my report a couple of months back https://www.nzhuntingandshooting.co....ession-109099/

As noted, the bottom line is your actual trajectory at a range longer than you’ll ever hunt. Use that to reverse calculate your velocity from a good ballistic app eg online JBM and take into account as much as you can like measured scope height above bore, range findered distance, local temp, barometric (station) pressure and any slope where you did the trajectory. Use paper not metal gongs. If youre really fussy w0rk from a tall target using a tape measure not dialling clicks for the trajectory test then do a click adjustment test of your scope.
