BBF,
While I agree with you on strictly a "numbers" standpoint, that if you run the ballistics programs for the '-06 and the 6.5 Swede and compare the two for downrange velocity, bullet drop and energy and the published bullet maximums', the clear winner on paper will always be the '-06.
However, what I was comparing was the two bullets being fired at the same velocity. Both at 2700fps. And when I stated that because of the SD of the 6.5 being better, I ment that's what gave it (the 6.5) the clear edge in downrange energy performance when compared to the 30 caliber, when the starting velocities were equal. Why?...well, because it's true.
And the book may very well tell you (us) that the maximum velocity for the Hornady 6.5 is 2600fps, but please come to my range and bring your chronograph 'cause you probably won't believe mine....but these bullets will go faster than that and still remain accurate and still provide excellent terminal performance.
Now, also on the "practical" side of "things" I know that the '-06 states the maximum velocity of those bullets will travel 3000fps, and I know that some guns will actually shoot a bullet at that speed or even a tad bit more, and they will shoot them accurately. However, most tubes...at least in the 30 calibers that I've shot, seem to be happier when the bullet is delivered a little bit slower. Also, the recoil is much better. Yeah....I mean much better....and I can't say that enough.
So, again, on paper it all looks good, but in practical terms, like recoil, and the fact that for deer sized game out to 300 yards, an initial MV of 2700fps will get the job done, the 6.5 bullet will do the job better than the 30 caliber. Less shoulder bruising, no flinching for the recoil anticipation, and usually a dead deer at the end of the bullet delivery.
And sometimes, it ain't all just in the numbers.
