This is hard to answer,and I don't profess to be the last word on tis or anything;just my point of view cause we are in a grey area.....I can only tell what I have seen.I think bullet action has a lot to do with it....

From the standpoint of tissue destruction(mostly fired from 7mm and 300 mags cause that is what I have seen the most),I've traced bullet paths through elk killed with both,seen the destruction,and would say (guess)that the 30 destroys more tissue,or seems to....

..after a long stint with 270's and 7mm's on large buck deer, I whacked a big bodied Saskatchewan buck 350 yards across a field with a 165 Partition from a 300 Win Mag started at 3250 fps.....I was a bit surprised to see the damage and size of exit wounds. I have seen the same thing on other animals and bullets fired from 300 mags.

But does the 300 "kill" quicker or "better"? I suppose it should....but I have not been able to detect it from the standpoint of how far the animals travel,given similar hits and comparable bullet action, and considering that no two shots are precisely the same.......

I think this is because,all things being equal,the 7mm destroys "enough" vital tissue,penetrates well enough,and creates enough damage, that the animal simply cannot handle the trauma......and I think also this is because ballistics is "Physics",or science,and in contrast to what happens to cause an animal to die from a bullet is something else,hard to quantify in certain terms.

I'd say the animals is in tough straits regardless which of the two he is hit with.....

These are my thoughts and observations on the matter....all contrary viewpoints welcome.. smile

The 280 Remington is overbore.

The 7 Rem Mag is over bore.
