[Bozos of Bones]

Yes, faster bullets more easily break bones and penetrate things, but wider bullets make bigger holes. Again, which is more powerful? The bullet with a bigger hole, or the bullet with a deeper hole?
I don't have access to ballistic gel, so unless you want me slaughtering pigs, I'll stick to wood.
Dr. Fackler disproved a whole lot of theories, and proved that the bigger the bullet, the more the damage. By "bigger bullet" I also mean expanding or fragmenting rounds. The weight of a pistol bullet alone is enough to cause some serious damage, and the surface of effect is larger too. Some rifle rounds fragment and turn inside the target, so do some pistol rounds. And what exactly did I say that Fackler would have a problem with?
