Excellent point.
For me, it's not that velocity kills better (it only does to a point, as in your example, then diminishing returns). It's that velocity best deals with the unknown 'wind drift' factor. Will 100 fps help...not practically...but going from a 30-06 to a 30-378 Wby (about +400 fps using 180gr bullets?) shooting across a canyon you gain significant wind advantage or call it margin of error, using same bullets, depending of course on how fast the wind is blowing and how far you can shoot at proficiently. If you judge wind and practice often, then maybe you can account for the wind properly almost each and every time but velocity may make up for the almost factor when you don't notice the extra downdraft etc. How do you normally deal with wind? It was blowing fiercely about 1 month ago when I was in Wyoming...
The Hammer Bullet claims are similar. That is, that you can increase velocity by 300+fps (if you think that traditionally a 300 Win Mag pushes a 180gr bullet at around 3100fps, then they are claiming that you can push their 178gr to 3400+fps, how or if safe and sustainable is the unknown), and all else being equal (hunter/shooting proficiency), does this extra velocity (or velocity from another method) make a difference on an animal at longer range if you misread the wind?
