Pocket ballistic calculator reduces stuff you need to carry on your range trip, then get everything setup and try not to loose or break things.
What do you think?
It will get you close but will not be exact.
One is actual, and the other is calculated and there is the difference.
The best way(Most accurate) is to chronograph at the muzzle and at 100,200 and 300yards.
At this point you have a very good idea of the Actual BC of the bullet And the velocity at those
From there the Calculated velocities will be very close at longer distances.
The chronograph also gives lots of other data that the ballistic calculator cannot, so one can't
replace the other.
It is an amazing tool but you still need a chronograph in my opinion.
