RE: two basic bullet theories
I'm gonna dissagree on the wound not bleeding. I don't know about high powered rifles. I hunt with a bow and modern muzzle loader. The deer I kill bleed like a stuck pig from the exit and entrance wounds. You can see it on weeds and trees or anything else on the way to where they keel over dead. I have even seen it running out of them when they stop to look around or jump a fence.
If I don't have something with a enough shock to knock it down on the spot, I want an exit wound as well an entrance wound. And I want to damege the least amount of meat possible.
That is what I have seen any way.
