Completely agree, there is no such thing as a "brush buster" even tests performed with a 375 H&H have given deviation of bullet path from small twigs etc.
My reasoning for a slow heavy bullet is more to do with lower impact velocities meaning less chance of bullet disintegration and/or massive meat damage.
I do not doubt the killing capacity of a .243 in close cover provided a suitable bullet, as you have mentioned, is used.
An 85gr barnes TSX pushed fast out of a .243 is a lethal combination!
Bullet placement still remains key and I don't think anyone meant that using a larger calibre was an excuse to shoot recklessly, however people are human and mistakes do happen and I believe the argument is that using a larger calibre could mean the difference between and anchored animal and one that you will never see again.
