Thread: Sub sonic 7-08

I'm wanting to load my 7-08 to run a sub sonic load for shooting around the farm.

I'm running a suppressed T3, 160gr cast proj and trailboss. I loaded some up tonight with 11gr of trailboss, but they are still super sonic.

How little powder can I use? If I'm only using 6 or 7 gr, do I need to use a case filler to prevent "flashover"?

Thanks
