Grendel as a Universal Infantry Cartridge

[stanc]

I don't see what would be wrong with putting a short boat tail on this, like the M193 55gr. Either way, that would be a great assault rifle load, especially if it was screaming at 2900fps. The longer we can extend the 2600fps lead shower threshold, the better. This would mean a thin jacket, and the cannelure helps with jacket separation in conventional projectiles. Put a penetrator buried in the core of the bullet, with a concealed hollow-point, and now we're talking multi-purpose.

You've used the "lead shower" phrase in other threads, and I always thought you were talking about the ability to hit the target with 5.56 more rapidly than with a higher-recoil round like 6.5 Grendel.

It looks like you actually mean the ability of the projectile to break up into multiple fragments?
