bigger diameter bullet is alwyas going to do things a tiny bit better if not more.
At least IMHO.
Jeff I agree. But I have sometimes struggled trying to figure where the lines are..
Lines are fuzzy to the extent you can't see them, UNLESS it gets chitty...
Bigger does better in a lot of things, bigger holes, better penetration(given the right bullet) and more energy.
Probably 99% of the time its never needed.
We could go the other way though too.. I"ve not shot anything much I can recall at this point in life, that a 243 would not have done just fine on. WEll there were a few LONG shots, but in reality, not large stuff, biggest was a caribou.. 243 would have been fine on them too..
Only moose I"ve shot have been close enough and right angles a 243 would have done them in too....
