To use BH209 you need to use the bare primer breech plug

I use 100gr to 120gr of BH with CCI209M primer and Hornady 200gr SST with Harvester smooth blue sabot. you can use these sabots.

Theres only three sabot you can use in your gun that's a good thing.so buy all three just to see what one your gun likes with what ever bullet your using.
