Jerry:

The "17 tons" is the long out of use bolt thrust standard derived in base-crusher guns. It isn't chamber pressure. Current standard for the Flanged Magnum's chamber pressure is 3250 BAR/47,137 PSI. Still way over the top. The rimless Magnum is 62,000.

Also, Taylor had his data wrong on this one. Original standard for the .375 Flanged Magnum was 18 tons, not 17.
