[QUOTE="DDB TX, post: 1530847, member: 64182"] Canhunter, I am not sure that heavier bullets are favored over faster bullets by energy comparisons, I think velocity is much more important. This is from the Wikipedia article on "muzzle energy" : "Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the square of the velocity. The velocity of the bullet is a more important determinant of muzzle energy. For a constant velocity, if the mass is doubled, the energy is doubled; however, for a constant mass, if the velocity is doubled, the muzzle energy increases four times." And this is why fast, relatively light but heavy for caliber 26 and 28 caliber rounds can compete with slower, heavier 30 and 338 caliber rounds in the big game field. Sectional density is very important too, for deeper penetration on big game and for energy retention at long range. For example, a 150 grain .264 caliber bullet going 3000 fps at the muzzle will have the same muzzle energy as a 150 grain .338 caliber bullet going 3000 fps at the muzzle; but downrange, the .264 will always have more energy at a given distance because of its higher sectional density.
