came across this video, very informative. A little disturbing, since they are talking about bullet impacts on human tissue. But the principle applies to animals too.

Basically, tissues have elasticity, temporary wound cavity caused by bullet with velocity below 2200 ft/s does not cause permanent damage.
Thus, for a 270 WIN, pass 300 yards, the killing power of the bullet drops significantly, and it is critical to have direct impact on vital organs/blood vessels.
Just some food for thoughts.
 
I'm not sold on your conclusions
big game animals (like bison) has been taken with slow bullets
permanent damage I would say
 
Actually I thought it was brilliant and mirrors what I’ve seen and have been beating the drum about on rifle velocities. I’ve noticed a distinct uptick in performance with cartridges that leave the barrel at 2,400fps+ on game in many, many examples. Turns out with a typical ballistic coefficient that nearly nails a velocity of 2200fps at 100 yards in most cartridges. I’m even more fond of a 3,000fps cartridge, as it pushes that performance drop off further away from the hunter. I rate a .270 above a .45-70 for instance in the odds of dropping an animal in its tracks, and on distance travelled after the shot. This 2,200fps impact threshold for stretch cavity tissue tearing makes complete and utter sense to me.
 
not trying to change anyone's mind on calibers, Sapiens been killing animals with spear and arrow for hundreds of thousand years. , we still have hunters killing animals with arrows. feel free to do what you are comfortable doing.

hunting bullet isn't full metal jacket, hunting bullet is designed to mushroom or explode upon impact, so there's a higher chance for fatal damage. most hunting bullet are designed to expand above 1800ft/s.

It's going to be easier to recover the animal if the bullet is traveling faster than 2200ft/s. especially in Ontario's thick forest. I've had bad experience with deer ran 100m with half of his heart. Just because I can hit a steel plate at 600m, doesn't mean I can kill a deer at 600m. So I guess after my 270 barrel kicks the bucket, I'm going to get a 7mm rem mag barrel.
 
It sure wasn't the FBI that discovered that velocities somewhat north of 2000 fps crossed a threshold into higher performance. That little tidbit was observed by the French in the 1880s, right after a guy named Paul Vieille first came up with what we would now recognize as smokeless powder. Hé vous avez vu ça? Il a assommé la fornication! La poudre noire est obsolète. Impressionnant!

The British were fairly adamant that a bullet could be big and heavy but if it wasn't doing 2100 it wasn't going to impress many elephants.


Comparing handgun cartridges is like sorting dog poop into neat piles.

If only someone would make bullets go fast and stay fast longer. It could head-space on suspenders.
 
Thank you for posting this very interesting video. The filming is top notch and seeing the ballistic gel in slow motion is very informative. Now I realize how my Nosler Partitions do their magic!
