The big tell me is:who has the absolute perfect instrument that will measure psi in a gun while firing?I reported on a method that I bought and used.The comments were not perfect.The one that concerned me the most was that I could be liable (at the time and now I covered that by being an LLC and buying liability coverage).I find that I am now very unlikly to ever post on this board.
