AMO Recommended Arrow Weight Chart

 

This recreation of the AMO chart is used to determine the minimum recommended arrow weight that you should use when shot from your bow. Many archers use the AMO recommended 6 grains per pound of peak draw weight to figure their minimum arrow weight.

However, the 6 grains per pound is figured using the AMO standard 30 inch draw length. In reality, depending on whether your actual draw length is above or below 30 inches means your bow will store more or less energy respectively.

In response to this fact, the AMO puts out this chart to prorate or derate the minimum recommended arrow weight depending on whether your draw length is above or below 30 inches.

  1. Select the column that describes the type bow you shoot
  2. Move down that column to locate your Actual Peak Draw Weight
  3. Move horizontally across the row to your "AMO Draw Length" column
  4. The box at the intersection contains the minimum total arrow weight for your equipment

Arrow weight inlcudes all arrow components - shaft, insert, point, fletching,
and  nock

Ex: Given a bow with; 30" draw length, 60# peak draw weight, & speed cam
     The minimum arrow weight is given as 365 grains.
