Stan;
Thanks for the up date. That number converts to 21,000 FPS. One can "Almost" call that going all at once.

I tried twice to send you a PM but don't think either went through, errors on my part apparently. I had a bit on setting off dynamite electrically that I thought you might find interesting but thought I had strayed off topic about far enough here. I will try once more later & see if I can figure out what I am doing wrong.
