Here's the process I use to make 25 Stevens reloads:
* Trim 1.403 length on 22 Hornets down to 1.130
* Run 22 Hornet brass in a 25 Hornet FL sizing die - to reduce the web
* Run the cases into a 25 Hornet Expander die to expand the case just past the shoulder
* Re-run the cases back into a 25 Hornet FL sizing die 
* Fireform the brass
* Trim brass to 1.125, the case length of a 25 Stevens
* Reloaded with either 7-8-9grs BP (original BP charge 10-11grs) and 3-4grs of 2400 smokeless  using the Lyman 257420 - 72gr bullet
Results that the reloads drop into the chamber with ease
