Are bonded bullets more forgiving of shooter error?

Understanding Bonded Bullets

Bonded bullets feature a jacket and core made from the same material, typically copper, which are fused together. This construction enhances weight retention and consistent expansion upon impact, making them more forgiving of shooter error. For example, a bonded 7mm Remington Magnum (RM) 150-grain bullet may expand consistently to 0.6 to 0.7 inches in diameter at 2,000 to 2,200 feet per second (fps), maintaining a significant portion of its original weight.

Kinetic Energy Transfer and Expansion

Kinetic energy transfer is critical for effective hunting, and bonded bullets excel in this regard. By retaining a substantial amount of weight and expanding consistently, bonded bullets can deliver more kinetic energy to the target. For instance, the 7mm RM 150-grain bonded bullet may retain 85-90% of its original weight at impact, resulting in a higher kinetic energy transfer compared to non-bonded bullets.

Hunting Elk with Bonded Bullets

For elk hunting, bonded bullets are a popular choice due to their ability to deliver a quick and humane kill. When hunting elk, it’s essential to use a bullet with sufficient kinetic energy to penetrate deep into the animal’s vital organs. A bonded 7mm RM 150-grain bullet can achieve this, with a muzzle velocity of 2,900 fps and kinetic energy of approximately 2,500 ft-lbs. This makes it an excellent choice for taking down elk at longer ranges while minimizing the risk of wounding the animal.
