Geez Luize it sure is tough to add anything to whats already been said here. About all I can add is related to military brass. Military brass is typically thicker than commercial brass so your internal case capacity will be SMALLER with the military brass. Keep that in mind when charging with powder. Smaller internal case capacity INCREASES case pressure, all other variables being the same.
Myself like a lot here that roll their own, have had the same experience that max loads never seem to be the most accurate loads. I stick to middle of the road, then experiment with bullet styles, bullet weight,powder types, etc.
