All above is so true. The only way I can make my own target loads is when I can get beyond blowout pricing on the components. By that I mean $1 for 250 wads, staff price on primers(thanks guys), hulls from spent cheap target factory ammo, and lead shot at a great price. Some powders are ok at retail, again buy bulk 8 lbs tubs. Then I wait until the darkest and coldest winter nights and plug away. Custom loads are nice to have, 7/8 shot works well shooting trap while stretching out the lead bag, and it is a hobby to boot. What ever you do..........do not think saving as in pistol or rifle cartridges. If you are not into bargain hunting stick to buying cases.
