Other = there is no one BEST hunting round, It is a personal preferance, they will all kill a deer at reasonable ranges with proper bullets with in the realm of there intended target.
we all have personal best and tend to tell everyone that the caliber we use is best period,
As for me I think the 30-378 weatherby is the best hunting round period, some might think its the 30-06 and still yet some will say their wildcat round is the best.
If you want to go by sales then the 30-06 and 30-30 are it.
There are better choices then minje and also alot better choices then the 30-06. But to each his own on this.
there have been more friend ships lost around campfires and bar rooms over what is the best hunting caliber, as there have been arguments about the .45ACP VS.9MM, and 1911 VS. Glock.
it will never be settled and all we can do is use what works for each of us.
