Comparing Theropod Teeth With Modern Hunting Weapons

So, personally, I hunt(both archery and rifle) and something about it got me thinking. Both methods are effective in taking out a deer, but they also have similarities in the way a theropod would bring down prey. Allow me to elaborate...

Archery and Slicing Teeth...

Both are designed to kill via blood loss. They cut and slash an animal open.

Bullets and Crusher Teeth...

Bullets don't cause the amount of bleeding arrows do, but cause a lot more trauma and shock, which is how they kill. The crushing teeth of many tyrannosaurs did the same thing.

Bullets result in a faster kill, as did the teeth of say, Tyrannosaurus. They shock and trauma they cause are usually enough to kill an animal. There is some bleeding, but not a massive amount. This is partly because they both are delivered with a lot of force. Arrowheads and the slicing teeth of say, Allosaurus, result in massive bleeding as they are designed to cut. But the amount of trauma is less, as the force behind the arrows/teeth is less than the bullet. It's a slower death, but a more painful and bloody one.

Basically, T.rex(crushing teeth) is like a high caliber rifle and Allosaurus(slicing teeth) is like a crossbow/compound. From now on, this is how I plan on comparing the two major tooth types seen in theropods. 

(I hope this makes sense. I'll be honest, it was hard to word this in text rather than actual speech).
