... except....ADI AR 2210* and adjust case capacity from a measured 36.3 to 39gr H20, I get a velocity match, but at 53.7ksi)
**Using H322 and/or ADI 2219 gets the same result, so the ADI MSDS sheet appears to be correct:
The XBR velocity result was a total surprise as it easily matches the ball powders, but is ~100-150fps faster than any of the other stick powders. Primers are no good for pressure signs and I'm obviously under the 70ksi brass-flow/ejector smear regime.
`Anyone else getting similar (or different) results, and does anyone have a handle on the pressures ?
postscript: I've found that adjusting QuickLoad case volumes show consistent relationships between stick powders (use 36.gr H2O) and ball powders (use 40gr H2O). So XBR is acting like a ball powder as far as QL is concerned.
