Page 47 states to never use more than 150 grains of powder.
The 2 pellet loads were just suggestion loads to get you going. I am not a pellet as I prefer to be able to fine tune my loads and pellets dont allow that.
I highly suggest you order a bag before attempting to shoot the strikerfire. The headspace is pretty loose and the primer, under firing conditions over time can cause damage to the frame. Drop this lil guy into the primer pocket and it damn near lasts 70 shots in our striker fire being needing replaced.
