I am not sure what you are indicating...
Hornady SST's will probably come with the HPH-12
The
new TC Shockwaves - should come with the HPH-24 or a black Harvester
The BULLET - SST or Shockwave are the same except the tip color - the sabots supplied are not...
If you are using Shockwaves and they are stiff getting down then try changing sabots to a HPH-24 or Black Harvester - if that fails them go to a Harvester "Crush Rib"
hope this all makes sense...
