“bc”

The all-new 6.8 Western brings the .277-inch bore diameter to life in a cartridge with a muzzle velocity that won’t burn up a throat prematurely, and offers the heavier, higher BC bullets that have been so popular among long-range shooters and hunters.

Engineers at Browning and Winchester teamed up to create a cartridge that offers magnum performance with a modern high-BC projectile, yet is chambered in a short-action rifle for shorter bolt throw and less weight. The 6.8 Western was designed to be the ultimate long-range cartridge that is capable in any big-game hunting scenario as well as long-range target shooting.

Hornady has reengineered its popular GMX projectile to be more accurate, aerodynamic and deadly. The new CX monolithic copper-alloy bullet sports a higher BC, and boasts devastating terminal performance with 95 percent weight retention.

Undoubtedly one of our nation’s favorite cartridges, the .223 Remington is capable of hair-splitting accuracy in a properly built rifle, has enough velocity for a respectable trajectory, and with the heavier bullets with a higher BC, can resist wind deflection rather well.

SIG Sauer is diversifying its big-game ammunition with Elite Hunter Tipped, a new line engineered for versatile performance at all effective ranges, and especially when long-range precision is critical.

Two measurements are thrown around quite often regarding bullet performance: sectional density and ballistic coefficient. Understanding these two terms gives hunters an advantage when it comes to bullet performance beyond the barrel.
