    Have a Remmy Target Short Action chambered in 240 PSP (Warren Page Sooper Pooper)
    What can I re-chamber this full cylinder barrel so that it stays existing 6mm and 0.473 bolt face?

    I want a 500 yard target rifle with a more common cartridge, no-turn neck and common brass and dies.
    Will a 6mm Rem reamer clean up the old cartridge?

    I don't know/have any information on this cartrige so if you post the case dimensions and/or
    the parent case it is made from we can probably help you.

    Thanks J E

    The best I can find so far is a fuzzy copy of a 1960-something reloading manual...
    0.472 rim dia., .471base dia., .402 shoulder dia..
    The shoulder is 1.820 from the rim and the brass is 2.221 long. I could be a little off because of the poor condition of the copy.

    I was hoping someone else had a more ledgeable copy.
    Anyone?

    Here is A drawing I scanned from A book.
    According to the Speer #5 manual the angle should be 28 degrees.
    I'm looking for A gunsmith that has A 240 PSP reamer.
    Can anyone help me out?

    A standard 6mm Remington won't but from that drawing it appears you could get a clean chamber with a 6mm Rem AI.
