Shootist,

I already got a response from CCS. The sabots are exspensive - $70 per 100 plus shipping. Starting load data comes with the sabots. Other needed parts like gas seals and cards are relatively cheap. They also sell loaded ammo but it's pricey at about $15 per box of 5.

Sabots are available for .451" or .500" bullets

She was kind enough to send me three documents with lots of info/pricing. If you like me to send them to you, just shoot me a PM with your email.
