Mike,
I agree with you, but the RN Hornady is a very soft bullet, were you to use a tougher bullet then you would get more of a drilling solid effect...

It is all about bullet construction at known velocity....as to internal damage and meat bruising...

I have shot many impala with big bores that you could eat right up to the bullet hole...a good examplel is the 250 gr. Nosler on Impala and I have used it many times on them as well as the 300 gr. Nosler, they will run a 100 yards and leave a light blood trail about every time and meat damage is almost none existant with that tough bullet, unless you strike a major bone...
