Follow-up by Medula Oblongata:
I've experimented with these up to 7.4 grains, but I would consider 7.0 to be the maximum that I would give to another person to shoot.
My notes (and other findings) related to the FN 5.7x28mm Weapon System (Ammunition, Five-seveN pistol, P90 PDW, PS90 carbine, CMMG Banshee Mk57, SCHV weapons in general, conversion of other weapons, accessories, reloading, etc.)
