HeviShot alone (#4) will run you about $2.50/ shell (1.25oz). Add in the cost of the wads (.10), primer (.05), buffer (.10) & powder (.20), you are looking at about $2.95 / shell (+/-). That is assuming you already have hulls.
Have not priced factory HeviShot loads, but I think it would be almost the same as 'roll your owns'.
