a short time ago a young fella asked about reloading the 9mm largo, and mention was made of the .38 auto. I have a star pistol in 9mm l (and reload for it), and came into a lot of .38 auto factory ammo. so comparison time. set up the coronograph (Oelher 35p); my hand loads did just over 1000 fps, the .38 auto did just over 1200 fps[:0]. next I got out my .38 super (Taurus 1911), same result.......so I tried some win. .38 super ammo (+p on the box).....I guess the 'Super' ain't so super after all.

    What did you get from the +P Win. .38 Super? I've got a bunch of .38 Super ammo (and a Colt Govt. I inherited from my father) and I think I might have some .38 auto stuff, too. I've got some 9 Styer factory ammo and that old "square" Austrian pistol. I've never run any of it over my Oehler 35P. I guess that's another project I'll have to put on my "bucket" list.

    That is interesting. Most data I find predicts a top velocity for the 38 acp of 1150-1250 fps. If that's really what the super was clocking in at something here speaks of a long standing myth.

    I extrapolated my own data by starting with 1 gr of bullseye and a 125 gr lead round nose and worked up in 1/2 gr increments until I got to one that reliably operated the gun (3.5 gr). With book max loads of 5-5.5 gr of bullseye I felt safe in doing this. It's mild, leaves the brass at my feet, and is pretty accurate to boot.
