So the question really is: when will a properly loaded 30-06 not work and we need something flatter shooting or harder hitting to hit/kill our intended game?
Working, after a fashion, & being optimum are 2 different things.
No problem at all with the '06 on everything but dangerous game & for that I simply want the security of a bigger bore & more HP with a heavier bullet.
If I had no choice but the '06, I think I'd pass on some animals.

Agreed with may not be optimum for some animals.
What animals/conditions do you feel it inadequate or you would pass on?
