History is amazing. A typical misconception is that 'grains' refers to the variety of grains of gunpowder or propellant in a cartridge. That is entirely wrong. The grain weight system measures the mass of the projectile. More grains = heavier projectile. This measurement relates to the complete weight of the projectile, consisting of the coat, lead inside, and any penetrator or other filler material, such as the chemicals made use of in tracer rounds.
