Ideal Weight for Crossbow Bolts — What to Consider?

April 6, 2026

Quick Answer

The ideal weight for crossbow bolts depends on the type of hunting, the crossbow's specifications, and personal preference, but generally ranges from 150 to 300 grains or 9 to 19 grams per bolt, with 200 grains being a common and versatile choice.

Choosing the Right Bolt Weight

When selecting the ideal weight for crossbow bolts, consider the type of hunting you’ll be doing. For hunting small game like deer, a heavier bolt weight, typically between 250 and 300 grains, is suitable due to its higher kinetic energy and increased penetration. In contrast, lighter bolt weights between 150 and 200 grains are better suited for hunting larger game like elk or at longer ranges, where arrow speed and range are more critical.

Bolt Weight and Crossbow Specifications

Understand your crossbow’s specifications, including the draw weight, power stroke, and arrow speed, to determine the ideal bolt weight. A general rule of thumb is to choose a bolt weight that is 20-30% of the crossbow’s draw weight to achieve optimal performance. For example, if your crossbow has a 150-pound draw weight, a bolt weight of 30-45 pounds or 200-250 grains would be suitable.

Additional Considerations

When selecting the ideal bolt weight, also consider state regulations regarding crossbow bolt weights. Some states have minimum or maximum bolt weight requirements, so be sure to check the regulations in your area before making a purchase. Additionally, consider using a broadhead tip, which can increase the bolt’s kinetic energy and effective range, but may require a heavier bolt weight to achieve optimal performance.
