“He didnt have 20 rounds.”
But he did have more than 0, and cause to use them.
And should have... Getting beaten nearly to death by 10 isn’t nearly as bad as getting nearly beaten to death by 20. Fewer people who want “their turn”.

For protection against mobs over-penetration isn't an issue. Just aim for center of mass and the closest one and let sectional density and velocity do the rest! The 10mm is the round of choice, IMHO for such situations, unless you thought ahead and brought your 10 gauge shotgun!
Doubletap makes all sorts of 10mm ammo, including the 230 GR Hardcast.
The heaviest and deepest penetrating 10mm in existence! This hardcast Wide Flat Nose Gas - Checked bullet will not deform on impact, and will create a large deep wound channel. Excellent for hunting or woods protection!
