In reply to:
In preparing tarage tables a dead weight or constant force is applied to the crusher.
Is this true for the SAAMI crushers? William Davis's article in the old NRA Handloading mentions crushers for the military are so calibrated, but that old American Rifleman article on base crushers hinted the tarage for that system included a fudge factor to try to get a better estimate of peak pressure. It was known in the 1800s that crushers underestimated the true peak.
