I enjoy comparing the performance and ballistics of different hunting cartridges which might be selected for hunting the same animals. In this case, I wanted to open a discussion of the 308 vs the 7mm/08 for use on African plains game or North American big game such as deer, elk, etc. I am not a PH but am a hunter with decades of hunting experience and have been to Africa a few times to hunt PG and DG. Even so, few hunters can amass a huge resume of hunting experience in one lifetime and I am no different. As such, my comments are my opinions based on limited useage of each cartridge on big game. That said, I wanted to share my experiences and observations to this forum which hopefully will prompt some of you to also share your hunting experiences with one or both of these cartridges.
What prompted me was a recent YouTube video posted by Joseph Von Benedict and Ron Spomer discussing all of the 30cal hunting cartridges and their attributes. Neither of them are fans of the 308, so it was rated pretty low on the totem pole. I was thinking about my own experience with the 308 and the 7mm/08 and how different those experiences were considering that the two cartridges were about as close to being the same as any two could possibly be. The 270 and 30-06 might be another similar example.
My early big game hunting experience on mainly deer and wild hogs was with the 308 using mostly 165g reloads and Nosler Ballistic Tip cup/core bullets. I chalked up an impressive run of one shot kills on both with this combo and only suffered one notable failure when using a Winchester Silvertip factory load that appeared to be unable to expand at close range on a deer forcing me to take 5 shots before killing the poor beast. I switched to a 270 after that and had similar good results. I have never lost an animal to either one. Fast forward to recent years and I took a nice old FN Mauser in 308 on my first African Safari for Plains Game. Loaded with Federal Fusion 180g bonded ammo, it took five animals from 30y to 202y, all with one shot and all with impressive terminal results. The little FN is not a tack driver. It is an ultra-lite pencil bbl model that is handy and capable of 300y shots on game but is usually a 1.5-2" group at 100y and about twice that at 200y. OK hunting rifle but nothing special.
For my 2nd safari, I was planning to hunt both Limpopo and the open plains of the Free State and was advised to bring a very accurate rifle capable of reaching out to about 400y as some of the critters in Free State were simply tough to approach. MY 308 has a clunky old vintage optic with a tapered crosshair and no provision for hold over or dialing for long range. That ruled it out. I have many rifles and considered my 270 Mauser but it is getting old and never shot the heavy for caliber bullets as well as it shoots the lighter 130g ammo. So, I ruled it out also. I considered a nice 30-06 but it is more of a mid-range rifle in many ways and in the end narrowed the choice down to my 7mm RM or my 7mm/08. The 7mm Mag was the logical choice but it has a 26" Looong bbl that is a bit unwieldy and since we were also hunting the bushveld of Limpopo, I liked the short light handy feel of my 7mm/0 a lot better. Both were the same rifle spec and both were legit 1/2 moa rifles. In the end, I chose the 7mm/08 despite its obvious lower performance over the 7mm Mag for a few logical reasons:
In summary, I found the 7mm/08 to be more accurate than the 308 and capable of making longer shots on game when comparing my two rifles but it lacked the impressive knockdown capacity of the 308 and lacked the decisive terminal performance. No game was lost with the 7mm/08 excpet for one Warthog that was hit but made it to a hole before expiring and was not recoverable. But, I was left with a bad taste in my mouth despite my wanting to like the 7mm. I know if I keep hunting with the 7mm. logic would suggest that it will over a larger sample size perform very close to the 308 when using similar bullets. When I get the chance, I plan to test that hypothesis.
I am sure that many of you have experiences with one or both. Please post your stories about your favorite bullets in each and how they performed for you or your worst failures as both can be instructional. Below is the FN 308 in Walnut & Steel and the 7mm/08 in Carbon & Titanium. Which would you prefer to take hunting?

- The 7/08 is shorter and lighter
- Just as accurate
- Similar in performance to other proven chamberings such as 257 Roberts and 7x57 Mauser
- Better performance than the much loved 6.5CM by most measures plus 6.5CM was not allowed in Free State as 270 was the minimum where I was to be hunting.
- Able to deliver a 140g TSX to 400y at over 2000 fps
- Was so close ballistically to my 308 that I was expecting similar performance on game
- The 7/08 scope was more suitable for hunting in close bush conditions like Limpopo than the magnums 3.5-18x optic and it was still good enough to achieve adequate 400y accuracy.
- While the 7 mag is able to send up to 160 and 175g bullets at adequate velocity the little 7/08 was sending 140g TSX or 139g CX bullets at similar speed and ballistic drop and while lighter, I figured the copper mono ammo would still penetrate well enough for my needs.
