These two calibers were invented to shoot the biggest

beasts within just a few yards, in thick vegetation,

or when you darn well expected a true charge. 577 is

usually lighter, for the guy who carries his own. Best

info is that with new proper bullets both penetrate more

than enough. I suppose, that there could have been some

small number of situations in past years/decades, in

which a 577 NE was used, and it "failed" so to speak,

and that if the man would have had a 600 NE, and fired

into the exact same spot on the beast, that the results

would have been as desired due to the extra energy from

the 600. I suppose. But man, really, how many times could

it really have happened? With that said I'd love to

shoot an old 600 NE to see what it's like, [I've fired

a new Searcy 577 NE]. And If I could handle shooting

the 600 that's the one I'd like to own because for ME,

that's the one, of the two being discussed, that has the

magic in my opinion.
