    A bit ago I started working up loads in .45 Super for my .45 ACP Enfield carbine. I'm currently getting 1-1.5 inch groups at 50 yds. and 2-3 inch groups at 100 with 9.5 grains of Power Pistol and 230 grain FMJ bullets. A friendly load with absolutely no signs of over-pressure. Can someone tell me the ballistic calculations for that load; pressure and Ft.Lbs.?
    Thanks.

    Guess I'll have to borrow a chrony. Is there any way to guess-timate using the known info?

    Not unless you tell us the barrel length of your Enfield carbine.

    If that were known, someone here with Load-From-A-Disk software can come pretty close.

    Ah, no problem...16.5 inches, built on an Enfield No.4 action.

    Power Pistol is as good as it get for 45 Super...but the 45acp (and 45 Super) don't get much help from barrel length past 6 inches or so.

    Your load is likely running right at 1,150 fps. (+ or - 50 fps, depending on chamber and bore specs)

    I get 1,000 fps from 8 grains of Power Pistol fired from a 5 inch XD. (230 grain XTP's)
