Grendel as a Universal Infantry Cartridge

[LRRPF52]

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.
