M855, M193 Bullet BCs

[RWBlue]

I am working on bullet drop.
I have real velocity numbers.
I need the Bullet BC M855 and M193.

Thanks

If you have a long enough range and good velocity data, you can figure it out from the drop between 100 and 200 yards, or 100 and 300 yards. Otherwise just check out Speer's and Hornady's website for the listed BC for their 55 FMJ-BT and 62 grain (Speer) offerings. That will be pretty close, and don't forget that often there is a delta between published BC and observed BC. Each barrel is an entity unto itself.

I was hoping that in the gov. wisdom that they had recorded true/observed BCs for these gov. rounds.
