i saw this statement in another thread and wondered what is the exact mathematical formula to make a boolit “heavy for caliber”.
Sectional density is used to quantify a bullet's weight relative to its diameter. Typically "standard weight" handgun bullets are around .17 to .19. The following are what 'may' be considered standard weights for their caliber:
.357 - 158gr
.44 - 240-250gr
.45 - 250-260gr
Anything heavier would be considered "heavy for caliber". Typically:
.357 - 180-200gr
.44 - 300-355gr
.45 - 300-360gr
It tends to be bullets in the .25 to .27 range that exhibit the deepest penetration. This is where the .357 and .41Mag's fall short because they just don't have the capacity for a bullet that heavy.
