Federal TSS shells are cost effective for the subgauges. Handloading doesn't necessarily make sense until you get into the heavy 12 ga loads. Of course, the point of shooting TSS is you don't need a 12ga or heavy loads.
Pay attention to how your handload will protect the bore from the shot. TSS will score your barrel if there is not something between it and the bore.
My data shows a wad with a Mylar liner inside of the wad.
