longnkrnch-
It might help if you would explain your reasons for wanting a carbide sizing die. I'm willing to learn about this.
My personal opinion is that a carbide die is not needed for reloading the 450B any more than a carbide die is needed for a 30-06. (Yes, there are some 30-06 carbide dies around, but they're really expensive.) Most carbide dies are intended for pistol cartridges. The 450B is a rifle cartridge.

Here's a photo of a set of zip-spindle Hornady dies (Image from the sinclair int'l web site). I'm curious what about them makes you suspect they wont work in a usual press with a 7/8-14 threads?

Are you perhaps confusing the "zip spindle" with the Lock-N-Load feature of some Hornady dies and presses. The lock and load equipment consists of a collar with inner 7/8-14 threads which you screw onto a die. The exterior of the collar acts as a bayonet-type locking device, so that you drop the collar with the die attached into the bayonet socket adapter screwed into the threads of the press. This allows rapid attachment and removal of dies from the press. Image below shows the press adapter on the left, and three die adapters on the right.

The Hornady 450B die set comes without the adapters. The dies should screw right into your press.
