Re: 7mm-08 vs. .338 Federal
I'd go with the .338 Federal. Here's why: yes they 7mm-08 and the .338 F have about the same powder capacity but guess what? The .338 burns more of it's powder in the barrel. Think of it this way, longer barrels burn more powder right, is it a function of length or volume of the tube? I say volume, and the .338 F with a barrel of equal length as a 7mm-08 has more volume in the barrel, it is therefore more efficient. When I first read the ballistics of the .338 F I was sceptical, then I ran one over my chrono. Holy Crap, I had to think long and hard about how such a small case could push a 200gr bullet at just under 2700 fps from a 22 inch barrel. The only thing that could explain it was the volume of the bore relating to the burn efficiency of the powder. Let me sum this up for you, both cartridges can go 2700 fps; the .338 Federal does it with 200grs while the 7mm-08 does it with difficulty with a 160 gr bullet.
