OK Let's look at a few things here. Maximum Effective Range. Most bullets are designed to perform at speeds of no less than 2000 fps. The distance it takes for the bullet reach 2000 fps is it's Effective Velocity Range. Energy needed to effectively bring down a deer sized animal is around 1000 FT Pounds, to do sufficient damage to make an immediate kill. The distance the it takes the bullet to reach 1000fps is it's Effective Energy Range. I'm a long distance shooter so this is an important issue with me. Below you will find the result of my search on these two and the comparison. I looked at all the differant bullet weights for each and selected the Maximum Effective Bullet for each.
25-06, 110gr bullet, 525 yards, 2023 fps, and 1000 ft lb. Sighted in for 200 yard zero, this bullet is 18.5" low at 400 yards.
7mm-08, 140gr bullet, 400 yards, 2000 fps, and 1243 ft lb. Sighted in for 200 yard zero, this bullet is 23.2" low at 400 yards.
As you can see, the 25-06 has the higher Maximum Effective Range, even thou it is shooting a lighter bullet. That extra 125 yards can make a big differance to someone like me. The 25-06 also has the flatter trejectory.
I have and would again opt for the 25-06 over the 7mm-08.
