Lew - thanks for posting these. The only Herter’s box I have is the silver on for empty cases, as well. I have 7 loadings in Herter’s, covering all three of the headstamps, but in my opinion, while none appear to be reloads (that is, fired before and reloaded), only one of mine is a factory loading. I have a GM RN SN loading with green primer seal and neck seal in the Swedish case and they look very much like the seals from Svenska Metallverken ammunition, the company I believe made the Swedish cases.
I I have one other in the Swedish case with whaqt loks like a factory-quality red primer seal, and it may be a Herter’s loading as well, although I doubt it was loaded by SM in Sweden even though the case was made there.
The 9mm is hard to pin down for Herter’s. I, too, have found no hard evidence that they offered loaded 9mm - certainly they offered loaded ammo in many other calibers, including revolver rounds though, and they are listed in the only Herter’s catalog I have, Wholesale Catalog No. 81 dated 1971 (pag 537). However, even in this catalog there is circumstantial evidence that they had offered 9mm as loaded ammunition. In the picture of a few rounds that appears at the head of the list of calibers, there is a loaded 9mm cartridge shown, even though no auto pistol round is shown in the list.
They show there revolver rounds as being in virign brass, loaded with Herter’s own styles of bullets, indicating the loading may have been done other than in the factories that supplied the cases. Of course, the case suppliers may have made the “Herter’s” bullets as well, or Herter’s may have supplied the bullets to the case makers.
At any rate, my guess is that probably a very high percentage of the Herter’s 9mm cartridges in collections are not Herter’s-loaded cartridges, but rather handloads on new Herter’s brass done by whoever bought them.
All of the bullets in mine are non-magnetic, not necessarily the norm for European loads, except the one in a Finnish case, which has a GMCS soft-nose bullet. However, soft-nose bullets are not the norm for Finnish ammo of the time, either, although that could have been specified by Herter’s.
All said and done, there is still a lot to learn about Herter’s brand auto pistol cartridges. I hope someone with a good selection of Herter’s catalogs can take the time to sort through them and see what they can find out. My catalog has a good index, which makes it very fast to find the ammo pages.
