Recoil shouldn't be a deciding factor. On average, you're looking at around 14# recoil energy for a 7-08 vs approximately 12# for a 6.5 CM. If ammo is tough to get locally and you'd rather not buy online for whatever reason, then the 6.5 CM will likely be more convenient to own. If you have a suppressor, then even less of an issue.
Cartridge | Free Recoil Energy (Ft-lbs) | Recoil Velocity (FPS) | Avg Bullet Weight | Avg Muzzle Velocity |
7mm-08 Remington | 14.88 | 10.68 | 160 | 2,672 |
6.5 Creedmoor | 11.87 | 9.56 | 138 | 2,695 |
6mm Creedmoor | 10.89 | 9.22 | 105 | 3,022 |
I added the 6 CM, because it has better recoil and velocity than both the 6.5 and 7-08.
Ironically, I'm buying a new Tikka T3x Lite in 7-08 today. Eurooptic is running a killer sale with a cart price of $699. They're also covering the sales tax ($42) and shipping is only $13. Throw in the $75 Beretta rebate, and I'll be all-in on a brand new Tikka SA for $640.
For others interested in the 7-08 that reload, you can get 162 ELDM, 160 TMK, and 168 VLD. If you really want to get wacky, you can even jump up to a 180 ELDM. I ran twist rate comparisons for all of these, and all are sufficiently stabilized by the factory 1:9.5 twist barrel. You lose a little BC at low elevation with the 180, but for guys out west, from around 4k and beyond its fully stabilized.
My long term plan for the 7-08 may likely be a 6 CM build, but for now I have hundreds of rounds of .308 brass that are one FL resize away from being loaded for the new gun.
