I remember the Herter days well even back to the 60's. Alzheimers hasn't kicked in yet.
I think their 2 shouldered cases were called "Ram Magnums" If a single "venturi" shoulder worked for Weatherby, hell, 2 of them were even better. I tried a few of their "Wasp Waisted" bullets, but in my guns the accuracy was not very good.
Somewhere on my book shelf I still have a reloading book by the Herters.
I bought several things from Herters including a few rifle and shotgun stocks. I think their idea of 95% inletted was way off, but the wood was always better than I expected.
I think their claim to the best in the world for all their products were really about, FOR THE MONEY you pay, you can't find something better. That part could be true. I have a die or 2 laying around, they worked fine, but other brands exhibit a lot better finish detail, course, they don't really work any better than the Herters.
I sure do miss the "days" when you could get stuff mail ordered and reading the Herter Catalog always made me smile.
