Reloading for 400 Astra?

newell asked:


I own an Astra 400 in 9mm Largo. It was for export to America and was chambered for 9mm Large or .38 Colt. NOT .38 super. Could I load .38 super for this gun, provided I lower the powder charge to .38 Colt levels?
sigh. I said this was a special export version chambered with a compromise chamber for 9mm Largo and .38 Colt Auto. .38 Colt Auto has much lower chamber pressure than .38 super, but identical dimensions.

    I would look into trimming cases to the Largo length and stick with the loads you find in a recognized re loading manual. If your pistol is, in fact, a Largo.

    If I read you right… dont try to mimic a .38 super loading… 38 super works at very high pressures and I would suspect an Astra would fail violently if a .38 super lever round was fired through it.

    Again …from you posting I am not sure if your Astra is actually a 9 largo … or 9mm luger or a .38 colt (short or long?)

    9 mm largo is an obsolete round from about the turn of the 20th century. There is only one match for it, namely the Winchester 9x23mm. Only the brass can be used for reloading as the Winchester is 75-100% more powerful than the Largo.
    .38 ACP & Super is a semi-rimmed round and cannot be used without turning the rim. Also it is .010 short.
    Now here is where the fun comes in: Find some 9×23 Win brass and some reloading dies.
    I did the research on the cases, now you do the research and find some.

    Apparently Old Western Scrounger has done just that.
    Please measure case volume carefully to be sure.
