Shame on you, Jim. You know very well that weight and velocity of ejecta are the only significant indicators of recoil and weight of powder charge does not enter the equation. Red Dot, Nitro 100, PB, and 7625 have very different burning rates and are not suitable for all the same loads, even though they may be suitable for some similar loads. Charge weight is not a factor in determining powder substitution except by coincidence. Should we change the title of this thread to "Old wive's tales of reloading"?
I hope you're joking! Just in case you're serious, the powder charge is most definitely part of the ejecta. If you are pulling my Legg, it's a bit longer now.
