A couple of things here are worthy of Note. I can't say about this test but I do know that Bell stated in some of his tests, they were taken with strain gages which had not been calibrated. This was in some of his tests where he was comparing smokeless reloads with black powder ones. For this purpose that was fine, but if this same method was used one simply cannot say that 5950 is equal to a factory pressure reading of 5950.
Also with a test of this sort one can only guarantee the pressure for that lot of shells. Next batch may not be the same unless the factory warrants them so.
