.577 Tyrannosaur.
Yes. It does with the right ammo. The issue is not the caliber. It's the ammo.This can be argued to the end of time. Bottom line is its gets the job done.
I would feel 100% comfortable using a .380 pistol with a flat nosed FMJ or with one of the few hollow point rounds loaded with the Hornady XTP bullet that actually expands and penetrates to acceptable levels.
