- -> at any given point during the powder combustion. This should indeed
- -> lead to higher chamber pressure. How much higher, I don't know.

- That brings up something I've been kicking around for a while. It
- would take very little effort to whip up a pressure test device using an
- old barrel - for example I could take a .357 or .45 revolver barrel and
- screw a cap over the end, drill the appropriate hole in the side for the
- pressure sensor, and use a solenoid and pin to strike the primer. No
- need for crude copper crush cylinders - you could measure the pressure
- directly.
-
- Has this been discussed to death here before? I could whip the thing
- up on the lathe pretty easily, but I'm at a loss as to how to handle
- the electronic part. It sure would be nice to have an actual pressure
- curve instead of a peak reading.
-
- With the pressure checker, you could safely test offbeat handloads or
- suspect ammo without harming your gun, and you wouldn't have to
- guesstimate pressure from the condition of the primers, case head, or
- astrological signs.
