And, unless I did my math wrong, Murdr's velocity numbers are a bit higher than those posted by TW.
That's correct. What I posted was average speed which is simply distance/time. It appears the numbers Tony provided are instantanious speeds. The average would always be higher than instantanious on a decelerating object.
I tested at the 300 and 600 meter ranges that Tony provided data for.
Time of flight at 300 meters was about 0.36 seconds. (it's hard to be exact when the degree of drop is so small)
Time of flight at 600 meters was 1.137
It appears faster at short range, but by the time it hits 600 meters, it appears slightly slower than the data Tony provided.
And by the way, the numbers I posted were more a comparitive measure between the two guns in the game, as opposed to precisicly measuring respective round velocity. There are factors that could skew measuring in game round drop to determine actual velocity, but it's the only method I could come up with to give a general idea of kinetic energy loss.
