You can find "book" formulas, using STS/Gun Club hulls, that will run around 6500 psi and mid-1100's fps with 7/8 oz, using either Alliant Extra-Lite or 700X. I prefer Extra-Lite, but it seems to be extra-hard to find these days, so I've been using 700X which does not burn as clean. In both cases, you're dropping less than 15 grains of powder, so they're also good economy-wise.
