Biggest cost is the shot. You save with lighter loads.
I load some 3/4 oz 12 G Lot of 7/8 oz and a few 1 oz. Some of my 12 G SxS's shoot 11/16 OZ very well and it's all you need for short clay targets. Most of the time load 7/8 OZ 7 1/2 to avoid changing the crimp adjustment though. Small volume run on the lighter loads, savings on shot not worth it.
Thing I like about loading short shells is you can tailor the load to the gun. No matter what the price hard to find mild loads suitable for SxS guns in some shot sizes.
