DidI mention anything about a .243?

I certainly don't recall it.

There is a lot more to clean kills than just saying that you need "X" ammount of energy. I can take a .357 magnum with a 180 grain cast core bullet and kill any elk that walks this planet. It generates a whopping 450 foot pounds of KE at the muzzle. And yes, someone that knows what they are doing could take a .243 with a barnes TSX and cleanly kill elk at 400 yards

You know I (others as well)try and try to be nice and not talk bad about you or post things in a derogatory manner and even offer advice to you concerning your own thread but it seems that you just like to piss folks off here.
