Yeah, science and truth suck so badly... having said that, I won't be responding anymore on this thread. It's too good to junk up. A new thread on shooting lead cows would be in order... as in, "don't do it, and teach your kids and grandkids not to."
The lead cow is the repository of generations of knowledge. Killing her eliminates that and hurts the herds ability to navigate migration routes. She also has a deep knowledge of food and water resources that younger members don't have... not shooting the lead cow should be elk hunting 101, but...
My first choice for the 7-08 and elk was a 140 (preferably an Accubond or Partition), but my particular 7mm-08 preferred heavier bullets (they often do - I've had 3 of them) hence sticking with the 150gr Ballistic Tip. I think @BuzzH has more than proven a 140 Accubond from a 7-08 is all anyone...
By "pushing" things you can probably achieve 150/2,750/20" - but to do it within SAAMI specs, it will take one of the "wonder" powders rather than something like the standard H4350 which will give you around 2,650 w/ 20"@ max SAAMI pressure. Thing with a lot of the "wonder" powders is often...
The "best" mountain rifle is whatever the "best" mountain hunter has in his hands. The world is full of great cartridges, the question is whether the hunter is up to the mountain and the shot. Familiarity with a rifle is more important than what it's chambered in, and physical condition is more...
I have had something like seven different 300 WSM's going back to 2001. I've taken antelope, mule deer, and quite a few elk with it. Anymore, I don't like its recoil, and haven't hunted with one for years. I prefer lighter recoiling cartridges and never found the WSM's added velocity necessary...
I've got that same book on my shelf - I always liked Cactus Jack.
Hunting means a lot of different things to a lot of different people. I'll use an analogy from a different field - my father started flying in the 1940's in an open cockpit tail-dragger. He went on flying through the Korean War...
