SST/SW - same bullet different tip & different sabots... SST comes with MMP HPH-12 and the SW come with HPH-24 -> black sabots...

SW also come now with the super glide sabot, also a MMP and Hornady now has now slimmer sabot also - also from MMP...

The super glide and the new hornady sabot are under contract to those two companies so humans like you and I can not by them direct but:

MMP does make a thin sabot that all can use it is the MMP HPH-3p-EZ load or you can go to the Harvester "Crush rib"
