That's true, but think of all of the other expenses incurred before you pull the trigger. Besides; how much is a two day pass at Disneyland? Which would you rather do? Hunt for a weekend or ride the Matterhorn? With fuel costs, lodging, license fees, food, gear etc. it's not like you're trying to save money to fill the freezer. (Don't tell my wife) Really, the ammo is your least expense. Now, if you were paying for performance that would be different, but you're not. (as Dan could attest)
If these rounds performed as good as comparable lead rounds the price would probably go down to more of an annoyance rather then a concern. Its kind of like paying Porsche prices and getting Yugo performance.
