I will never kill more elk with a single cartridge, than I did with a 25-05 when I was young. Shooting all of those elk with a 25-06 is the exact reason I use much larger rifles as an adult. The energy sucks for elk. It's a marginal cartridge, and most people damn well know it. You can drop one with a .243 to the heart... hell I've seen a bull killed with a .17rem right between the eyes. Allow a margin of error for a less than perfect shot by using more gun. Show some respect to the elk, which live in country where rests are imperfect, wind is a factor, and at altitudes that can make steady breathing difficult after a scramble. When you're out of breathe from scrambling over a rise, trying to nail a bull that's about to disappear.... (or staring at a trophy with a less than ideal angle).... you'll realize that the perfect shot isn't always the shot you get.

What's your argument again? If you're an "energy" guy, and you believe in the mythical "1,500 minimum" for elk, this load meets your "requirements" out to 700 yards. Marginal? I think not.

EDIT:

For comparison against the .30-06 and 6.5 PRC, two universally renowned elk killers, the .25-06 holds it's own and then some.

My wife shot this one with a twin-turbo 6CM with a whooping 990 foot pounds. I kept waiting for the old girl to get up. There is enough data on RS alone to prove the point that energy means nothing! Bullets matter!!

Example
{\displaystyle \mathrm {TKOF} ={\frac {Mass\times Velocity\times Diameter}{7000}}}

Example calculation[edit]​

Using the standard 7.62×51mm NATO cartridge, the cartridge's characteristics are:

  • Bullet mass = 9.5 grams
    \Rightarrow
    147 grains
  • Muzzle velocity = 833 meters per second
    \Rightarrow
    2733 feet per second
  • Bullet diameter = 7.82 millimetres
    \Rightarrow
    .308 inches
The calculation is:

{\displaystyle \mathrm {TKOF} ={\frac {147\times 2733\times .308}{7000}}=\mathrm {17.9} }

Therefore the Taylor KO factor for the 7.62x51mm NATO cartridge is 17.9.

Note: The product of mass and velocity is a quantity called, in modern physics, "momentum". Conservation of momentum is a characteristic of non-deformable collisions. A bullet, hitting hard bone, would transfer most of the impulse to that bone mass.

That's a big cow !! Congrats to the missus. What bullet? Was it a twin turbo?? Please excuse my ignorance, not familiar with twin-turbo

There we go.
Thanks for the link. I did a quick search and saw only two cows and one bull, so I guess 0.25" isn't sufficient. I've always heard something about width as being important.

So if I'm understanding this TKOF correctly, including from this site (https://thebiggamehuntingblog.com/what-is-the-taylor-ko-factor/), the 6CM (TKOF of 10.9 cited) only kills half as well as my 30-06 (listing a TKOF of 21.8)? Does it matter at all that he's been dead for over 50 years?

What's the desired TKOF for elk?

I love 25-06 but I’m mostly a deer hunter so I can’t comment on the elk. But to compare a broadhead to a bullet, just doesn’t make sense

I guess it depends on which side of this debate one falls on. From a logic perspective, it's hard to say that a 25-06 (as an example) is insufficient to carry, but an arrow with a broadhead is (in each case ignoring brain shots and other red herrings). And if the BH works, but not the 25-06, what about the latter fails? The diameter, the velocity, or something else? And what is sufficient?
