Whats the best way to check a B.C.

With all the variations in B.C. from one bullet brand and type to another, whats the best way for a long range hunter to compare the B.C. of one bullet against another?

Looking to reduce any errors as much as possible. So is it better to shoot and compare or just measure the bullets and calculate a new form factor?

Re: Whats the best way to check a B.C.

best way is to shoot it thru an accurate chrony at distance, say 1000yds. make a shield for it so you dont smash it etc.

shoot a known low ES load thru the chrony at the muzzle and take an average speed, and set it up again at 1000yds and measure same load again. its an almost perfect measurement, only error being the accuracy of the chrony and the slight variation in your ES, although this would even out if you averaged it out over 10 shots say...
