Hi,
Bob Dietmeyer, owned Pacific and designed all the Presses.
I have the first progressive 12Ga. press made, a DL-300 (Dietmeyer Loader!)...
Bair owned the foundry and made the castings for Pacific and then made for himself.
He and Bob had a falling out along the way and Hornady bought Pacific, or that is how I remember it.
Bob was a character, he would come in to work hung over and in a bad mood and fire everyone in the office and by the afternoon...
Be begging everyone to come back to work! Ha!
