M903 slap .50bmg


#1

hello

Does anybody have a drawing (or a good photo that can be uset to estimate measures) of the tungsten projectile (less sabot) for M903 SLAP round? Also, what is the weight of the penetrator?

I’m trying to estimate its ballistics by computing BC for this projectile and then entering it into ballistic computing software

Thank in advance for any help

Hello Maxim,

There is some ballistic info in this excerpt taken from Olin Military Ammunition catalog (1993):

Some more here (TM43-0001-27, April 1994):

Thanks
I wonder is projectile weights shown are for penetrator only or with added sabot

on a second thought, it appears that 415 gr is weight with the sabot and 360 gr is for bare penetrator. Am I right here?

Hello
length : Projectile = 46,21 mm - Sabot = 31,50 mm - Penetrator = 36,98 mm.
Diameter : Penetrator = 7,70 mm
Mass : Penetrator = 23,10 g.
V25 = 1220 m/s

Max, I have some (very small!) velocity, energy and time of flight graphs for this from a publicity sheet, I’ll scan them and email to you.
