Buddy of mine shoots a .243 savage and has had GREAT luck with Hornadys Superformance SST's. He's wanting to get into reloading, and likes the aggressive velocities with the Superformance for flat shooting and down range ballistics. Anyone using this? The 8th Manual doesn't cover it, and Hodgdons website doesn't have anything he's looking for. Wanting to use an 85 or 87 grain pill.
