Re: Muzzle Velocity
A very good Chrono.
Set the screens up at least 10' from the muzzle. Shoot 5 or 10 shot groups to get your average.
A good chrono will have ES and SD numbers to help with load development.

Re: Muzzle Velocity
First read the directions to the very good chrono, then shoot as many rounds as the chrono will give you an average for. As we all know an average of 3 numbers will not be as acurate as an average of 100 numbers.

This is more of where I was looking to hopefully go. I was talking to a few military friends of mine who were saying that they have a program that takes the input of their chrono'd MV and then gives them a range that is 3/4 through the supersonic flightpath and just nearing the transonic path. This is the range at which they will place a target. They then shoot and measure the difference between their POA and their POI and plug that measurement into this program. It supposedly then gives them a closer MV as well as a BC.
Am I out in left field here, or are there programs like this available? Their program is made by the military, and is only for standard issue match .308. Im hoping to find a similar program for 338 250gr lapua mag and .50 750 gr sniper elite.
