680 Foot pounds.... These threads are awesome.... I am out
This formula, just like measuring energy, doesn't take bullet construction or minimum expansion velocity into account. There are way smarter and more experienced guys on here than me that have piled up big game in the hundreds without a .30 cal or magnum. Visit the threads that guys have posted on this thread already and tell us if the real world changes your mind. Ryan has already posted 3 examples of dead bulletproof elk killed with pea shooters with impact enery far under the mythical 1500 minimum.Example
Example calculation[edit]
Using the standard 7.62×51mm NATO cartridge, the cartridge's characteristics are:
The calculation is:
- Bullet mass = 9.5 grams
147 grains- Muzzle velocity = 833 meters per second
2733 feet per second- Bullet diameter = 7.82 millimetres
.308 inches
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.
Time to head out west with my 22 WMR! YA BUDDY!
I really dosen't make any more difference to me than it probably does you, but to the guy that dosen't know any better, traveling 100s of miles and that may be one crack at an elk, that individual may not want to push the envelope with minimums. But we are all adults and make our own decisions. Good luck.
I guess I've got to ask, TMK?

came here to mention this, IMO if you're looking for the maximum distance your round will be lethal, the minimum expansion velocity is more useful than some arbitrary "minimum" energy required.This formula, just like measuring energy, doesn't take bullet construction or minimum expansion velocity into account.

Indeed, since the table I pasted in here already debunked the 1500lbs of energy and "marginal" comments regarding the .25-06 as far out to 700 yards.How does he or you determine minimum?
^^^This right here...came here to mention this, IMO if you're looking for the maximum distance your round will be lethal, the minimum expansion velocity is more useful than some arbitrary "minimum" energy required.
There are legal minimums that can vary across the country, but I get your point.but to echo all the other comments, there is no "minimum" caliber, it's down to what the individual shooter is comfortable with shooting, at their comfortable range, where they can reasonably expect an ethical kill
I’m in same boatI really dosen't make any more difference to me than it probably does you, but to the guy that dosen't know any better, traveling 100s of miles and that may be one crack at an elk, that individual may not want to push the envelope with minimums.

Yep, sometimes it’s the nut loose behind the stock that makes the differenceMany years ago sitting by a campfire, a guy told my 13 year old son that his 25-06 shooting 115 combined technologies was too weak for elk. Next day my son dropped a nice 5x5 bull at about 150 yards in his tracks using that gun.
The very next year that same guy shooting a 300 winchester with 180 partitions, gut shot a bull and never recovered it. Life is funny sometimes.

Elmer Kieth killed everything w 357 mag and lead solids? Someone did…. Sure doesnt hit those numbers.“”
Taylor Knock Out Values.
And it uses the estimated energy for one shot kills on game.
It uses a recommended energy and a minimum energy for each animal.
On Elk it recommends 2000 ft/lbs and 1500ft/lbs as a minimum. this is at the Point of Impact.
Deer are 1200 ft/lbs and 1000 ft/lbs minimum.
These values are conservative but are a good place to start.
You could use less energy but the results would vary especially if shot placement was not
the best.””

i typically follow this rule of thumb, I like DRT because I hate tracking
But I thought marketing of cartridges didn't happen before hornady invented the peashooter 6.5cm???Indeed, since the table I pasted in here already debunked the 1500lbs of energy and "marginal" comments regarding the .25-06 as far out to 700 yards.
My guess is, like I did a couple years ago until being enlightened by RS experts, he and other naysayers on this thread are still drinking the marketing and dogma kool aid from a bygone age.
You sir, are living my dream!680 Foot pounds.... These threads are awesome.... I am out
