Well we are getting pretty far from the original topic (which I dont believe that anybody actually disagrees with - this extractor that extractor = meh)
I also dont believe that any of the thoughtful reloaders on here believe that looking at a primer can give you any real information, perhaps measuring case webs is better but nothing a reloader can do can tell you what pressure they have reached.
Are we any worse off than the big boys though?
Copper units of pressure, lets all drill a hole in our chambers + its wildly inaccurate - MINT. Piezo transducer - similar problem.
Strain gauge compares deformation of the chamber area of your barrel during the shot to the deformation produced by a "reference load" - now if you can provide me with an actual real live "reference load" which you are using to calibrate your instrument then I will gladly swap one for as much rocking horse shit as you can carry away with some pixie dust to lighten the load. Why are strain gauge pressure figures never published I wonder? Yes its a tool they will use because it shows a trend nicely, but go on then = explain to me how this actually measures pressure inside a chamber and explain how that chamber can be compared to another in the absence of a calibrated load. (crickets chirping etc)
I will try to dig up the thread later, but the Strain guage dude was left with his dick in his hand (I will resist saying it was Ken Oehler till I find the thread, but im pretty sure it is him)
