Back 'shortly after the requirement became mandatory' he wasn't hand loading steel because there were no components.

PSI is PSI and it matters not what the payload is.

SAAMI max is 11,500 PSI for 3" 12 gauge.

You have no idea what pressure factory shells are loaded to, lead, steel, or anything else unless it's stated.

'Thinking I had nothing to lose'. Taking a 1907 gun out to 3" and feeding it early factory steel is certainly an interesting experiment.

Glad both he and the gun survived... that would have been way outside of my comfort zone.
