    I have a peck of old 38-40 brass that I am planning to put to use with light loads. All the reloading manuals I have call for large pistol primers, but the primer pockets in these are the size for small pistol/rifle primers.

    Just wondering when the manufacturers changed to large pistol primers--jumping to the conclusion this is the reason all the manuals call for that size.

    Anybody know this bit of history?

    It was around 1929.

    Another question. A few of these cases are Rem-UMC and have the large primer pocket, but all are the "balloon" type. So, when did the drawn/solid base shells make their appearance?

    The difference is inside. Don't think I could take a shot that would show it. Maybe later today I can section one of the shells that is too corroded or bent up to use. Then the difference would show.

    Here is a photo of a shell I sectioned. Very corroded, but shows the primer cup arrangement of a "balloon" type shell.
