Re: noob question
I don't know about Speer #14, but in my Speer #12 it is listed as 7mm Mauser.
The cartridge has gone out of favor. I don't think any modern guns are being made in it, although occasionally Ruger will make a small run of 77s, or Remington will make a small run of 700s, chambered in "classic cartridges", and they might make a few hundred. These get snapped up quickly by those that know and love the round, and then there are, again, no new guns made for it.
