Re: 338 bullet BC results from Snipers Hide
The results are real. I was one of the people down-range working the laptops for the chronograph during the test.
Other than Doppler radar, this was the first test (that I am aware of) that simultaneously tested velocity for a projectile at the muzzle, then again at roughly 300-475, and then again at 1,000-1,175 yards. for each shot. The results for 10 shots for each projectile were recorded.
Granted there are aspects of every test that can be done differently by the people running the test, and this was only the first on what we expect will be several demponstrations.
