The most efficient hunting cartridges

Very helpful, thank you. It really confirms for me that I'm on the right track narrowing down my new hunting cartridge to either 6.5 Creedmoor or .308 from my current .30-06 Tikka T3. I've finally admitted that recoil is affecting my accuracy and want to step it down a bit.
 
Well, I know what will crack the top ten

I am the first to claim that new developments in cartridges are the work of marketing teams seeking to excite the interests of novices and flakes. What, after all, do the new "inovations" achieve in terms of performance in the hunting field or the range?

What does the 375 Ruger do that the H&H can't? The same goes for the 300 WSM versus the the 300 Winchester Magnum.

The miniscule, trivial advantages of the newcomers appeals to those who read a lot of marketing tripe as opposed to spending time actually shooting and hunting. Fools who pour over reloading manuals and gun magazines and touts statistics and imagined advantages simply cannot admit they have fallen sway to hype. I count myself among seasoned shooters in sticking to the tried and true and condemning the new cartridges as the property of fools.

Then, after the passage of a suitable period of time, and without acknowledging my duplicity, I buy a rifle in 300 WM and in 375 Ruger. The sight of new brass holding a high-tech bullets is irresistible. More than anything else, it provides me an excuse to buy a new rifle. And while I am at it, I buy a few classic rifles in classic calibers so I can ponder the differences between the old and the new.
 
Interesting comparison here comparing a couple of my hunting rifles and their current respective loads :

6.5 Creedmoor 140gr Accubond @ 2855 fps
45.0grs powder
BC .462
Recoil = 15 ft lbs
500y energy = 1230 ft lbs
Ft lb bullet energy per ft lb recoil = 82.0

28 Nosler 154gr Hornady Interlock RNSP @ 3113 fps
81.0grs powder
BC .220
Recoil = 28 ft lbs
500y energy = 682 ft lbs
Ft lb bullet energy per ft lb recoil = 24.4

Any idea how the efficiency of the 28 Nosler might be effected if you used a higher BC bullet? Seems like that might help it retain more energy at 500y.
 
6.5 x 54 M-S.

Low recoil so almost everyone can shoot it well and high sectional density with those long, slim 169 grain softpoints. Bullet placement is everything.

Just have to master the Karamojo Bell shot for those elephants.................
 
7x57 using quality 173 grain hunting bullets in the 2300-2400 fps muzzle velocity range seems to be a sweet spot for medium and large sized white tail. It just plain works!! I've been a 7x57 convert for the past decade. 139 grains in the 2700-2800 fps muzzle velocity range is also effective. I don't need any of the 6.5 offerings.

I prefer 150 grain loads in the 7X57....tried them all and get the best results with the 150's.
 
I haven't used the 150's, but I have no doubt about their effectiveness. My current working rifle, a Brno "21" ('Z' gun), likes the heavies.
