I don't know about other die manufacturers but on my Redding 17 Hornet bushing neck size only die I unscrew and remove the sizing button from the stem but leave the decapping pin in place and use it like that. It's a tight enough fit the pin doesn't fall out.
I'm not really much of a Lee Precision fan but their decapping die is very inexpensive, I bought mine on Amazon for $10.50, and it works well. The decapping pin that comes with the die only works on 22 cal and larger but Lee sells a 17-20 caliber replacement pin for that die and it only cost 4 bucks. Makes for a pretty inexpensive decapping setup.
