Kirk, Ballistic Products Inc is a great source for data and components.

I use a lot of their products and shoot a lot of RST shells. Get their Advantages Reloading Manual. It has a TON of data especially for Cheddite, Rio and Fiocchi hulls. They've added more data for Rem and Win hulls in the latest manual.
