I use Wano 2P, but 3f/p is also said to be an appropriate granulation.
I use the two piece/Reiffenhausser (sp?) style that everyone else spurns for reloading and save the compression formed stuff for nitro; the two piece have a greater capacity and tend to develop lower pressures than the others. I trim them to length with a pocketknife once I've seated the over shot wad and roll crimp them.
BP melts holes in them, but they're free!
The looks at the range are priceless if they're not used to BP! I use them at Hamilton SSAA occasionally; the first time they thought there'd been a blowup!
The Tom Bullock page is superb.
