IMHO, nothing --- bullets through the vitalsare bullets through the vitals, still the same today.Some cartridges do more than others on their way "getting in there" and while they are "in there"and offer more ways for the hunter to "skin the cat" than others in terms of a wider selection of viable shot opportunities. Some folks may complain as they think that is cheating, but that is an ancient argument.

Remember, that in 1906 when the 30-06 came out there was similar b!tch!ing and moaning from a whole genre of black powder fans and even the "then only 11 years old" smokeless powder 30-30 affectionados! So complaining about the new stuff as being overkill and not needed is a fine and long established American tradition. Misguided but a fine heritage.

Why not embrace both the newer (the RUM's, the WSM's, the Lott, etc.) and the older (22LR, 30-06 (1906), 416Rigby (1911), 375 HH (1912) and all the great stuff in between . Create a well spaced rack of rifles by picking from which ever group you like according to the limitations you are willing to acceptand then match sufficiently strong tools to the "caliber" of the game being pursued and have at it....

It just can't beTHAT hard.

It is GOOD to have choices!
You don't have to buy it if you don't like it.
