    130gr. bullet
    59gr. / 4350 @ 3200
    60gr. / 4831 @ 3080
    65gr. / 4831 @ 3390

    150gr. bullet
    56gr. / 4350 @ 2950
    58gr. / 4350 @ 3030
    62gr. / 4831 @ 3150

    all powders are from IMR, and most are max loads. Ackley says there is little improvment in velocity to be gained as the case is already overbore.

    looking at the numbers you have posted it appears that the 270 Ackley will have an increase in velocity of a little over 9% on the 130 gr from accepted levels (Normal max 3100fps) and just under 9% for the 150's. (Normal max 2900fps.)

    Thanks for the info.
