William,

Reason I ask the question is your statement that none of your tests got above 10,000 psi is counter to tests by other ballisticians I know that have an industry standard pressure gun and calibrated gauges. You might find it interesting to contact someone like Tom Armbrust and have him send you a few known pressure loads to see how your setup compares. It can only improve your confidence and knowledge. As an alternative you could pressure test some loads in your setup and send several loads from the same lot to Tom and see how they compare that way. He is in that business of testing other folks loads and is really a great guy to deal with.
