38spl with lg primers

[jculloden]

Picked up some Remington brass at the range, looks like 38spl with large primer pockets, is this something old or new

I'm not sure about .38 Special, but early .357's (1935-6) had large pistol primers.

Sharpe mentions this in his handloading book; apparently the .38 Special was loaded with both small and large primers. Dates aren't given, but present tense is used, leading one to believe that both size primer pockets were available when the book was compiled in the 1930s.

Do they have the REM-UMC headstamp? The only 38 Special rounds I have had with large primer pockets were old ones from the 1930's with this headstamp.

I have some old .38 ACP cartridges (USCCo) with LPPs. Probably not unusual for different manufacturers to use different primer sizes at different times. Of course there are .45 ACP cases made today with small primer pockets.

Rem only headstamp, don't look that old

Definitely not calling you a liar but this does not add up well and makes very little sense if this brass is anything younger than 80-90 years old.

Pictures would be most appreciated here.

Many of the companies are moving to small primers where large have traditionally been used (.45 ACP, 10mm Auto) and there is a tremendous benefit for them from a volume production standpoint in doing this.

To willfully and purposefully go the other direction? And for a 17-20k PSI max cartridge? This makes no good sense that I can imagine.

I have a few LPP 38 sp.. I am also certain they are Rem. I read that they were made up to the mid 50s

38 Special cases with large primer pockets, wonder if they are balloon head cases?
