With my 6.5x25 WSSM I decided to spec the reamer so that a standard non bushing FLS die would size the neck turned case correctly. This gave a good, regular thickness neck thickness and meant I could use a dirt cheap standard 25 WSSM FLS die. For seating die I bought a 6.5mm blank Wilson die and had it reamed with the barrel reamer to fit.
As I also had a hard time finding 25WSSM brass here in Australia, my last batch of ammo was with 243 WSSM brass which I fireformed with a light load during a club day.
I do recommend you anneal cases after necking them up as the WSSM brass if prone to cracking if you don't anneal after necking up
