I am amuzed by the "the deer died so how did the bullet fail?" crowd. First off, fairly often it takes a second or even third round to finish the job. The deer died right?

What if a "frangible" bulllet FMJ'd through, then the deer ran off several hundred yards, bedded down and eventually died? Did the bullet not fail? The deer died right?

What if a bullet breaks into multiple pieces (hypothetically, lets say a TSX), but it killed the deer. It didn't fail right? The deer died didn't it? It's hard to pull a "failed" bullet (or pieces) out of a living deer right?
