Yeah but with a slower velocity in reality.

As the .333 Jeffery has the same velocity with a 250 gr bullet, then the above statement applies to it as well.

So by this sort of reasoning,

A .333 or .318 is the same as a .30-06.

Some claim a .30-06 is just the same as a 7x64.

Some claim a 6.5x55 is the same as a 7x64.

Some claim a .243 is the same as a 6.5mm.

And lastly some claim, a .224 is the same as a .243.

Therefore using mathematical formula, the .224 is the same as a .318 or .330. Therefore I might as well just stick with my .222.

I think the actual use of a calibre is much more important than often meaningless academic comparisons, as the above ludicrous example amply shows. I think its history of having killed thousands of cape buffalo and many elephants speaks for itself.

Tophet,

"The .333 is based on the .404 case."

Damn. You have made it more interesting again.
