I have to disagree.
It really doesn't sum it up.
The OP didn't ask if it was worth it. He asked if it were more economical. Big difference.
Whether or not something is worth it is subjective. Something that is worth it to you may not be to me, and vice versa.
Whether or not something is more economical is a matter of fact, not opinion. It is either cheaper or it isn't.
I will stand by my original statement.
The OP is comparing the cost of components with the cost of factory ammunition and asking if reloading 223 is economical when compared with factory.
The "worth it" is implied in this case.
I will agree with the rest of the comments on the value of worth to each individual.
