Hey Guys,

So for years now it always comes up .270 better than this or that. etc....

When deciding what is better than another where does bullet weight come into play?

Said another way, how can we compare a .270 to a .308 if they shoot completely different bullets?

Should retained energy be the measurement?

On another level I'm wondering since there appears to be lots of factors, kick, bullet weight, amount of powder, trajectory etc... if there couldn't be a mathematical model that quantifies a cartridge. Basically every cartridge gets a number based on it's factors. Does this make any sense?

Ok I'm done rambling let me have it.

Tom
