Both sets of these dies will be hard to find without have them made to order.
What I have done with Wildcats like these is to buy a set of bushing dies for the parent cartridge and use the appropriate bushing to size the neck.
That will depend on the brand of brass and whether or not you are going to turn the necks.
Good Luck

Thanks, Grafs have the 22-284 dies. I have a set for the 257STW, but I just picked up another 257 STW and thought if I could find a second set of dies I would pick them up.
I was hoping someone would have a used set laying around they weren't using.
Thanks
