Very good post & sure throws some Meat into the discussion. One question, in your opinion what does cause the 900 psi pressure rise of the Fig 8 over the RXP12. That is about an 9.2% increase. Certainly the difference in the wts of the two wads would not account for a 9.2% increase in total ejecta wt.
