Does increasing arrow weight improve penetration on larger animals?

Understanding Arrow Weight Dynamics

When it comes to arrow weight, a general rule of thumb is to use an arrow that weighs 2-3% of the bow’s draw weight in pounds. For example, if you’re drawing 60 pounds, you’d want an arrow that weighs 1.2-1.8 ounces. However, the optimal arrow weight also depends on the arrow’s length, material, and the type of game being hunted.

Effect of Excess Weight on Penetration

While increasing arrow weight can improve penetration, adding too much weight can actually decrease performance. Excess weight can cause the arrow to become unstable in flight, leading to reduced accuracy and increased deflection. Additionally, heavier arrows can put excessive stress on the bow and its components, potentially leading to damage or failure.

Optimizing Arrow Weight for Large Game

For larger game like elk or moose, you may want to consider using a slightly heavier arrow, but not so heavy that it becomes unstable. A good starting point is to use an arrow that weighs 2.5-3.5% of the bow’s draw weight. For example, if you’re drawing 80 pounds, you might use an arrow that weighs 2-3 ounces. It’s also essential to consider the arrow’s kinetic energy, which is calculated by multiplying the arrow’s weight by its velocity. Aim for a kinetic energy of at least 100-120 foot-pounds to ensure deep penetration.
