Subsonic Deer Hunting

[d-mon]

I have a little philosophical question ?

The 300 whisper is from around the early 90's if my memory serve me well.
I find it a bit bizarre that 20 years later we are still at such an early stage of discovery in term of bullet performances on animals and game, penetration, killing power ...etc

What do you think?

Mind you, It took a while for Jack O'Connor to convince the rest of the world of the performances of the 270 winchester.
