Time is money?
Some people don't seem to understand:
It's NOT about the money.
Money is simply a way of quantifying something to be measured.
Some folks (most here on the forum, I think) would load whether or not it saved money on ammunition. For me, asking how much per hour I save (or pay) is simply satisfying a curiosity.
If my thinking about the question offends you, I am sorry... that you cannot accept a different world view than your own.
