How much energy do 180-grain .300 bullets retain at distance?

Bullet Energy Retention

When hunting with a .300 Win Mag, it’s essential to understand the energy retention of your bullet at various distances. A 180-grain bullet, which is a common weight for this cartridge, experiences significant energy loss as it travels downrange. At 300 yards, a .300 Win Mag shooting a 180-grain bullet at 2,900 ft/s will retain around 1,300-1,400 ft-lbs of energy, more than enough to take down a large elk.

Ballistic Coefficient and Its Effect

The ballistic coefficient (BC) of a bullet is a critical factor in determining energy retention. A bullet with a higher BC will retain more energy at long range than one with a lower BC. The .300 Win Mag typically uses bullets with a BC between .475 and .550. For example, the 180-grain Hornady ELD-X has a BC of .535, while the 180-grain Nosler AccuBond has a BC of .495.

Practical Considerations for Long-Range Shooting

When shooting at long range, it’s essential to take into account the bullet’s energy retention, as well as other factors such as wind deflection and bullet drop. To compensate for energy loss, hunters can use techniques such as adjusting their aim point or using a reticle that takes into account the bullet’s trajectory. Additionally, choosing a bullet with a higher BC can help minimize energy loss at long range.
