the 308 out performs the 7mm-08 factory loads because of the heavier bullets. refer to fusionammo.com. Look a the graphs. with 1500 fps as my self imposed standard for hunting. the 7mm08 120 gr fussion to about 230 yds, the 7mm-08 140 gr fusion to about 300 yds. For the 308 150 gr fusion to about 350 yds and the 308 180 gr fusion to 400 yds.
trajectory is about the same as the rule of thumb, 2-0-8-24. That is 2 inches high at 100 yds, 0 at 200 yrs, -8 inches at 300 yds and -24 at 400 yds.
So my pick is 7mm-08 and 308. I pick them both. I have to say my tikka t3 7mm08 is fun to shoot. Light recoil and accurate. My BLR 308, bought in the 60's, is a bit handier.
Sorry, look at the Winchester Ballistics calcutator found at Wichester.com. With factory ammo the 7mm-08, 140gr power point does not have more energy than a 308 150gr power point at 200 yds.
As far as the 7mm-08 shooting flatter then the 308. I don't think you can tell the difference by pulling the trigger. I have taken mule deer, black tail deer, and a Big Black Bear (squared 6'9", 10 " ivory)
Never-the-less, I love to shoot my Tikka t3 in 7mm-08. And is now my new best rifle.
If you buy a 7mm-08 for the wife do not shoot it, or you just may end up buying one for your self.
The 308 w/ 180 does out perform the 7mm-08 w/ 140 (energy). Again that is paper ballistics.
So you've booked an outfitted hunt this year. And you're going to get to ride horses into the mountains to save your legs and your back.
I've met lots of guys who've been in this same situation. They figure, "heck, how hard can it be?" But, I assure you, if you don't learn to get along with your mount for the week, it's going to be a bumpy, scary, noisy, and life threatening experience.
First, let's start with the horse itself. A horse trained under western style has 4 gears. The walk, trot,...
