antique primer size bewilderment
 
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.

Thanks Hawg!

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?

Have any pics? Would like to see the differences in antique stuff vs "modern" stuff..

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.

Ah, OK. No need to ruin anything for my amusement..

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