    "P" proof on un-fired barrel

    http://www.gunbroker.com/Auction/Vie...Item=125805934

    Someone educate me. It's my understanding that the P proof marks on usgi barrels was applied after passing a controlled test firing with a higher pressure round. How can a barrel, new in the wrap, have the p proof without ever being fired?

    Initially the Ordnance Department required all barrel manufacturers to proof fire all barrels that were intended to be used in the Barrel Free Issue Program before they shipped from the point of manufacture. As carbine production proceeded the requirement to proof fire all barrels was relaxed to only 100 out of every shipment of 1000.
    The Ordnance requirement to proof fire barrels is why barrels packaged as replacements often have proof firing marks and why some barrels have two different proof marks, one applied by the barrel manufacturer and one applied when the assembled barrel was proof fired.

    BTW barrels were proof fired in a special fixrure. Bill Ricca posted a picture of Springfield Armory's set up on the old CSPicon site.

    Brian,
    By that late of date, wouldn`t Underwood been using the large P proof? When was the change over to the large P roof format?

    An Underwood barrel of that date wouldn't necessarily have a large P proof mark. That would indicate that the barrel was used by Underwood. Many of their barrels were sent to the "Free issue" program and were subsequently used by other manufacturers and would subsequently bear their proof marks, not Underwoods.
    When they tell you to behave, they always forget to specify whether to behave well or badly!

    This is just like and with the same date, the barrel I bought from George (before I knew better). It looks just like the fake he sold me!
