As title suggests, thoughts and opinions please. I am taking 30-06 but my mate is taking 7mms 08.

100 grains in the right place is better than 1000 grains in the wrong place. Cheers
The only thing I will point out, though you are right about the SAAMI specs, is that in any rifle made after 1935, the 7x57 can be boosted up to modern pressures easily and easily out-performs the short 7mm-08. I have had this discussion with people regarding the 6.5x55 vs 260. Loaded to modern specs, the old rounds beat the short rounds hands down due to their larger case capacity. Plus if you load it to equal the modern round, you will have a lower pressure load and that is more important I think. SAAMI really isn't the authority on 7x57 anyway. CIP is. Norma is showing a load in the 7x57 using Norma URP powder that will push a 170 grain bullet to 2,650fps. Plus... if it suits your fancy, you can tell people you have a .275 Rigby.... Plus the 7mm-08 has zero romance. It's a tool. The 7x57 has it in droves. One is a set of socket wrenches, the other is a Lie-Nielson Jack Plane. There, that was my defense of the 7mm Mauser... And I don't even OWN one!The 7mm-08 will outperform a 7x57, every time. This is due to the 7mm-08 being a more modern cartridge, thus loaded to a higher average pressure then the 7x57. SAAMI calls for the 7mm-08@61,000PSI while the 7x57 is only at 51,000PSI. The 7mm-08 will be faster with all bullets, Hodgdon shows the 7mm-08 with 160s averaging about 2650fps from several suitable powders. The 7x57 is only at 2500 with a 160, and that's with only about 2 powders. Most were significantly less. In addition, the 7mm-08 has a much better reputation for accuracy, being used quite a bit in various disciplines. The 7x57 generally has a reputation for attaining satisfactory field accuracy at best. The 7mm-08 is a true short action cartridge at 2.80", where as the 7x57 is not a short at 3.071", but really isn't a long action round either. It is just long enough to not work well in most short actions, due to limiting COAL greatly or not fitting at all, but a long action is much more than is needed. Most cartridge discussions are based on subjective feeling, but to me, this is one of the objective ones with a clear winner. The 7mm-08 Rem.
