There are basically big jaws and small jaws.
To me, that is .223 small jaws.
Mauser case head and 300H&H head, large jaws.
Everything else is ....see if what is already mounted will work.
My problem is those springs popping out when I drop the assembly on the floor. If I have to stop handloading becuase I lost a jaw spring, that could raise my blood pressure and kill me:(
I have figured out a way to make the jaws quick change from large cases to small cases. I just have to buy an extra set and drill some holes.
It requires $50 more parts from Forster for another set of jaws. [I know more than one person with two Co-ax presses to overcome this problem, but I took it as a challenge.]
I drill a counterset for a small flat head screw in the bottom of the wear plate.
028271-046 WEAR PLATE $3.60
That plate appears to be hardened steel, and has to be counter sunk with a carbide drill.
The screw is use is a 4-40.

I drill and tap into the shell holder jaw housing.
028271-037 SHELLHOLDER JAW HOUSING $14.80
With that tiny screw installed, the springs and jaws are trapped between the housing and wear plate. The screw can be removed for cleaning, but mostly the assembly stays together as a unit.
I bought an extra set of jaws.
001231 LOWER SHELLHOLDER JAWS--S(STANDARD)$29.60
028271-039 JAW PRESSURE SPRING (2) ea.$1.44
Instead of the Allen head screws now used to hold down the jaw assembly:
028271-020 10-24 X 5/8 INCH BUTTON HEAD SCREW (4) ea.$1.55
I use a knurled head screw that I would capture with a plastic collar or wrap of wire under the housing, so the screws can not fall out when not on the press.

I have two jaw assemblies, that I can drop on the floor, pick up, and install and use in 10 seconds.
The jaw swap is now fast like the die swap.
I can now swap jaws from big to small in 25 seconds with a drop the jaws on the floor step included.
a) The screw holding wear plate to housing makes it so I don't loose springs, even if I drop it on the floor.
b) Having two swappable jaw sets makes it so I don't loose springs.
c) I bought 10 springs.
I now have belt, suspenders, and duck tape.
And yes, I have notified Forster of my drastic improvement in their product, but don't hold your breath, they have never incorporated anything I have ever said to them. My only other suggestion was to de burr the de burr on bullets seaters, so the bullet doesn't get stuck or marked up in the seating process. I see they still don't do that.
