Hmmmmm, let's do some arithmetic.
Say you can buy a box of 20 gauge AA shells for $8.50 (including tax). That would seem to be a pretty good deal today, right?
Now let's say that the cost of the components to load a box of 20 gauge target loads is about $4.50 (not counting the cost of the hull).
So, by subtracting $4.50 from $8.50 we get $4.00 which is what you are paying for once fired hulls.
If we divide $4.00 by the number of hulls in a box (25), we get a cost of 16 cents per hull. So, it would appear that anything under 16 cents per hull for clean once-fired 20 gauge Win AA hulls would be a good deal, right?
