A correction:
Sometimes my fingers type faster than my brains or something.
The unit of impulse is the lbf*s or pound force second, NOT lbf*ft/s as I stated in the previous post. The expected range of numbers from 0.5 to 0.8 is correct.
Also, for factory loads where I have not actually weighted the powder charge I assume 5 grains.
