I can't figure the velocity of a .30 cal projectile with a 50BMG powder load behind it! Would have to be a stout bullet to hold together.

I can't figure the velocity of a .30 cal projectile with a 50BMG powder load behind it! Would have to be a stout bullet to hold together. As always, barrel length makes a difference, but circa 4000 FPS is quite possible. But the bullet doesn't need to be that strongly constructed, since the rifling contacts the plastic *sabot* guide and pressure seal instead of having the bullet jacket scored by the rifling.
More on the M903 .50 SLAP ammo here, and also on the SLAP-tracer round.
