What Is Grain Measurement In Archery? (Perfect answer)

The GPP of an arrow is equal to the overall weight of the arrow divided by the poundage of the bow used to shoot that arrow. The total weight of the shaft, nock, insert, point, and fletchings is included in the GPP total. A light arrow has a completed GPP of 5 to 6.5 grains for every pound of draw weight, depending on the weight of the arrow. A midweight arrow weighs between 6.5 and 8 grains, depending on its length.
