And remember that the A5 needs something to buck up against, to work. And if that isn’t there it won’t. An example might be hanging it from a string and then firing it.

Point being, if you want reproducible results, the test set up has to be reproducible.

Try two different loads of wildly different pressures, same speed and ejecta.
You probably won’t feel a difference, yet could blow the chamber or barrel on an old gun

What good would that do?
