It appears that 2.5 cc's of powder equals about 37.5 grains.

Shuetzen powder still seem very different according to BLE but I'm not sure why. I redid the calcs K seems to be about 1400 ( my mistake). Calculations I find to be fun BUT THEY SHOULD REINFORCE THE CHRONO RESULTS. I think they do in most cases. You can't argue with a chrono.

Nice post showing the formula from Don Miller. So, I have created a calculator using his formula and some "new" powder data.
