To provide an accurate measure of your chrono velocity you should provide highest/lowest of a fair sized sample and then calculate standard deviation.
Oh, it's a nit-picky game we're playing here . . .

PowderBurns Black Powder / Muzzle Loading Forum:
I think that it's fair to say that handloads loaded up to factory "advertised" velocities in .308 will equal or exceed factory .30-06 in most instances. By the same token, .30-06 handloaded to a reasonable working maximum pressure will come close to equaling most factory .300 Win Mag loads. Can the animal tell the difference? Usually not, but knowing your ammo is actually performing to expectations can give the hunter a psycological edge.
