Don, I actually had my post written that way but reconsidered because if I am able to blow up or damage a barrel in some phase of the test, the pressure sensor may be damaged. Another reason we (or I) won't do it that way is that it is too hard to coordinate the loading of the shells and the conduct of the test together with the location of the pressure testing aparatus. If you know of a way to simplify the whole process and also get an unpaid volunteer to do the work, you be sure to let us know.
