stopping power of a caliber and terminal effect of a bullet

I have stopped two motivated bison in their tracks with a 280 Remington shooting 140 TSX’s and a 7MM Mashburn and the 145 LRX. Lights out now. I have also been charged by three Grizzlies. Luckily no one including the bears received a scratch. One pulled up inside 10 yards. Neither time did the cartridge I was packing enter my mind. My ability to shoot straight went through it, what felt like, a million times. Every time I had someone with me and keeping them away from my muzzle was also sharply present.

You let a grizzly charge inside 10 yards and you didn’t kill it?!
 
Glad they work for you.
I'm an Elmer Keith fan...he was one of the 1st big names to write of it IIRC.

It is a real theory... but continue to 'do you' by all means

î found interesting that we came from a discussion to terminal bullet to now only one option ... look up a little of the modern bullet design and show how they do not work while the flat fat meplat is the only answer.

look up kynoch design and you will see what i mean and it was used long time ago ...
 
I let a charging bear get within 10 yards of me and the only reason I didn’t shoot him is my rifle was tied to my pack :(
 
I took a headshot on a mule deer buck that was looking right at me. The bullet hit a bit low - punched him right in the nose. All of the bone in his snout was shattered. The bullet only penetrated so far. It was found having tumbled down his wind pipe. The bone fragments from his snout entered the rest of his skull and terminated him instantly. He couldn’t have known what hit him. It looked like some piano movers dropped a big one on him. Couldn’t even see his movement to the ground. He completely buckled.

180gr nosler accubond @ 2700 FPS. Distance maybe 40 yards. 30’06 Springfield with 24” bbl. I didn’t keep or weigh what was left of the bullet but I’d say it was maybe 1/3 it’s original size at a guess.

Hit a running whitetail with a 140gr acubond from a 270 Winchester. The deer flipped ass over head and died on the spot. It landed in such a way that it’s head was facing in the opposite direction than it was just running. It was now ass first and upside down. Of course, the bullet did his the spine.

I’ve used 30-30 170gr something or other cup and core to great effect. Deer hit right in the boiler dropped like a bag of rocks. I love the 270 for many things but I have found that a tough bullet from the 270 In the boiler does NOT drop them like a cup and core 30-30 load. They run a bit from the 270 and die on the spot with the 30-30 in my experience.

Was with the old man when it took more than one shot to put down a big bodied, northern, bull moose. One shot from two calibers ... a fragmented bullet split in two was believed to be a nosler bullet that failed to put the animal down, but it’s hard to say with two deformed bullets. It was a big caliber too .. a bullet may not do what it was designed to.

Before my time, but the old man and his crew moved up to 30 cal type rifles once they moved up north for the hunts where the animals are bigger. His buddy’s 270 worked fine in the smaller southern moose, but fell short up north.
