5.7 in Home Defense

[Todd.K]

If we discount velocity, there is no difference between a 5.7 and a 5.56 using light bullets.

Unless we do something totally unheard of, like test it in a calibrated tissue simulant and see how much damage each cause.

Assuming projectiles optimized for their respective velocities, we can both predict which will cause more damage.

Except there is no optimal bullet for 5.7, because like the .380 it lacks the energy for both expansion and deep enough penetration.

Thus my point, a non expanding 5.7 has about the same wounding potential as a .22 mag.

To be clear I couldn't agree more, Todd.

Welll....the Lehigh Defense pistol bullets have been testing well in a few cartridges.

Perhaps one designed for 5.7 would be worthwhile? But then again, being solid copper, they are long-for-the-weight bullets and may not work with the 5.7 case / rifling.
