Down range OOMPH will meen different things to different shooters.
For instance, mathematically one bullet may clearly have more 'OOMPH' over another but wont expand and just pencil through whereas the other bullet may have less mathematical energy or 'OOMPH' but opens up and expands effectively and transfers the 'energy' to the game. In a way, the latter would have better 'OOMPH' than the bullet that didnt expand.
The below statements are my opinions only.
The best all around long range OOMPH factor goes to the 208 AMAX. Ran in a 26" 11x barrel at 2500 FPS she will have 926 pounds of mathematical energy and enough retained velocity for at least some form of expansion at 1K in standard air. I have run them as high as 2550+.
A good second is the 200 SGK. A fairly low minimum impact velocity requirment (1500 FPS according to Sierra) and a decent hunting bullet design with a decent BC. My accuracy load is 2500 FPS but have run them safetly over 2600 FPS. At 2500, the impact velocity threshold is just over 750 yards. Where this threshold is crossed there is also 1000 pounds of energy. From a hunting stand point the 208 AMAX and 200 SGK have the most 'OOMPH' at long range in a 308. Other bullets may have a better OOMPH factor in other 30 cal cartridges due to the higher velocities achieved. When you factor in the lower starting velocity of the 08 you need bullets that will have a better than average BC and lower than average minimum impact requirments. This leaves the Nosler Ballistic tips, Hornaday AMAX's & BTSP's, Sierra game kings and other simple lead core bullets.
Honorable mentions for LR OOMPH are the 168 Nosler BT, 168 AMAX, 178 AMAX, and the Hornaday 190 BTSP. Not in any specifec order.
When small critters are encountered such as wolves, coyotes, javalina, bobcats and other vermin the 155 Berger, or 155 AMAX are very tough bullets to beat. Good BC's at good velocities with phenominal accuracy and very low recoil.
Remember, these are only my opinions.
