Quick Answer
The 33 Nosler cartridge is expected to transfer approximately 80-90% of its kinetic energy to a big game animal, resulting in a lethal wound. This is due to its high muzzle velocity and flat trajectory. The cartridge's energy transfer is ideal for taking down large game at longer ranges.
Ballistic Properties
The 33 Nosler cartridge features a 33-caliber bullet weighing between 250-300 grains. When fired from a rifle with a barrel length of 24 inches, the cartridge achieves a muzzle velocity of approximately 3,150 feet per second. This velocity is maintained at ranges of up to 500 yards due to the cartridge’s flat trajectory.
Kinetic Energy Transfer
The kinetic energy of the 33 Nosler cartridge is calculated as follows: kinetic energy (KE) = 0.5 * m * v^2, where m is the mass of the bullet in pounds and v is the velocity in feet per second. Plugging in the numbers, we get KE = 0.5 * 0.25 * 3,150^2 = 1,245 foot-pounds. When 80-90% of this energy is transferred to the animal, we get a lethal wound.
Hunting Techniques
When hunting with the 33 Nosler, it’s essential to aim for the vitals: the heart, lungs, and liver. A shot placement of 6-8 inches off the center of the vitals is optimal for maximizing the energy transfer. Additionally, hunters should aim for a 45-degree angle to ensure the bullet enters the animal’s body and transfers its energy effectively. This technique is particularly useful when hunting at longer ranges.
