When presented with all the "proof" of the superiority of one caliber over another, my first thought is always, "So what?". If a person's ideal rifle is one that launches a round nose bullet at 2500 and does what he requires of it, it's a good rifle for him. Now, if he built this rifle with the idea of shooting at 1000 yds, he may have taken a wrong turn, but it is a fact that good results can be had with outfits which are, theoretically, less than optimal.

PS. If I wanted a 30 mag., my first choice would be a 308 Norma or a 30-338.
