Is there any formula to get the actual muzzle velocity in a reading from
a chronograph 10 ft. from the muzzle.
What would be the muzzle velocity from my 7mmSTW if Im getting
3114fps at 10 ft from the muzzle??????????
At sealevel it would be 3120.00. Not enough of a difference to worry about. You will get more fluctuation then that from the day to day difference in temperatures.
