6.1 grs of Silhouette will get you between 1200-1230 FPS. Depending on bullet used and length of barrel. One of my favorites. I use this powder to make 9MM major ammo so...

 

8.3 grs of AA#7 will get you 1250-1300 FPS. Again depending on bullet and length of barrel. I really like this powder for 147 gr JHPs.

 

Seat JHP 1.090”-1.100”. Keeps empty space in case to minimum and aids in reliability.

 

I would say use at your own risk but....duh.

I would also check with ypur bullet manufacturer to see what the reliable expansion velocity is for the bullet you plan to load.  Some bullets are sensitive to velocity as they expand.
