2 1/2" spreader load wanted

[Andy]

I have a lot of 2.5" RST hulls, once fired and would like to load some spreaders. I cut an RST apart, it's the Dispersor X wad and what looks like Green Dot. Here is what I have

Cheddite Primers
Clays
Am. Select
Green Dot
Longshot
572
700X
Spreader X wad
Spreader X Short wad
X inserts
Other BPI wads on hand: Short range crusher, piston skeet, brush wad

I want 12g for clays mostly in the Parkers 7/8oz of shot is fine. The BPI data seems to all be pretty stout stuff and I can't find 2.5" data for what I have on the internet or on this site. Thanks in advance.
