How is it that the loading manuals will have starting values for powder charges and then maximum values for loading charges and then the manufacturers will have much greater powder charges?
I pulled Winchester white box 9mm ammo and found a spread from 5.4 grains to 5.9 grains of W231 in the cartridges.
The loading manual says 4.8 grains is the maximum charge.
