Due to this fact, by way of bullet diameter, the .308 is definitively larger than the .270. The .308 bullet is .031 inches wider than the .270 bullet, offering a bodily benefit that interprets into heavier bullet weights and potential kinetic vitality advantages.
Analyzing Ballistic Efficiency: Trajectory and Vitality
Understanding how a bullet flies via the air is essential. A number of components affect a bullet’s trajectory, together with its weight, its preliminary velocity (muzzle velocity), and its ballistic coefficient (BC). The ballistic coefficient is a measure of how effectively a bullet cuts via the air. The next BC means the bullet is much less affected by wind resistance.
When evaluating the .308 and .270, we see some fascinating variations in these variables. .308 Winchester cartridges usually use bullets that vary in weight from about 150 to 180 grains, generally heavier.
