    duPont data, as reprinted in 1964 Handloader's Digest:

    .45 ACP, 230 gr FMJ + 5.7 gr 5066 = 830 fps MAXIMUM
    .300" seating depth (case length + bullet length - seating depth = OAL)


    NRA Handloader's Guide, 1969 edition
    data from H.P. White Laboratory

    9mm P, 116 gr Norma FMJ + 4.5 gr 5066 = 1102 fps @ 30,838 psi
    (Really CUP by current testing and terminology.)
    1.15" OAL

    Copy and pasted from here:
