Using the Easton Hunting Shaft Size Selection Chart

Once you have determined your Correct Arrow Length and your Actual or Calculated Peak Bow Weight, you are ready to select you correct shaft size:


Reading the Easton Hunting Shaft Size Selection Chart



The chart indicates that more than one shaft size may shoot well from your bow. Shaft size in bold type are the most widely used aluminum sizes, but you may decide to shoot a lighter shaft for speed, or a heavier shaft for greater durability and penetration. Also, large variations in bow efficiency, type of wheels or cams, bow length, string material, and release type may require special bow tuning or a shaft size change to accommodate these variations.

"Shaft Size" column - indicates suggested shaft sizes.

"Shaft Model" column - designates arrow model.
"S" = XX78® Super Slam® shafts. Also XX78 Camo Extreme™ Predator® shafts in sizes 2213, 2314, 2413, and 2514. 2613 is available in Camo Extreme only. (7178 alloy)
"75" = XX75®, Autumn Orange®, Easton Classic™, Advantage™, Camo Hunter®, GameGetter® II and GameGetter® (7075 alloy)
"E" = Eagle® shafts (5086 alloy)
"A/C/C®" = Aluminum/Carbon/Competition shafts
"P/C" = Pure/Carbon shafts

"Shaft Weight" column - indicates bare shaft weight only.
To determine total arrow weight, add the weights of the shaft, point, insert, nock and fletching. Where two Aluminum shaft models are shown for one size, the weight listed is for the XX75. Letter codes A-C listed to the right of shaft weight indicate the relitive stiffness of each aluminum shaft within that "Shaft Size" box ("A" being the stiffest, "B" less stiff, etc.).

Tuning-Although Easton has attempted to consider most variations of equipment, there are other style and equipment variables that could require shaft sizes other than the ones suggested. In these cases, you'll need to experiment and use stiffer or weaker spine shafts to fit your situation.

Insert Weight- If you shoot one if these sizes and use an aluminum RPS insert, add to your point weight the extra weight indicated to compensate for the heavier, tapered-shoulder inserts.

Determining Correct Arrow Length




Determining Actual Peak Bow Weight


Determining Draw Length
Your Draw Length is used to determine your Actual Peak Bow Weight for recurve bows, and to select the proper draw length setting for compound bows. To determine your Draw Length, use a lightweight recurve bow with an extra-long arrow and have someone mark the arrow at the back (far side) of the bow while you are in a comfortable full-draw position. Your Draw Length is the distance from the mark to the bottom of the nock groove.

Compound Bow:
Determining Actual Peak Bow Weight.

To shoot properly, the maximum draw length of a compound bow must be set to your Draw Length. A compound bow reaches its maximum or peak bow weight before reaching maximum draw length and then "lets off" in draw weight 50 to 80%. This reduced weight at full draw is called the "holding weight." The Actual Peak Bow weight of your compond bow can be determined on a bow scale at your archery pro shop.

Recurve bow:
Determining Actual Peak Bow Weight.

Actual Bow Wight (maximum of "peak" bow weigth) of a recurve or longbow is the force (in pounds) to pull your bow to your full Draw Length. See "Determining Draw Length" information above. Then measure the force required to pull your bow to your Draw Length ( most pro shops have a bow scale). THe AMO-standard bow weight is usually marked on the lower limb or handle. For each inch your Draw Length is over or under the AMO-Standard (28"), add or subtract respectively 2-3* pounds of bow weight.

*Approximatey two pounds per inch for bows 40# and under, and approximately three pounds per inch for bows over 40#.


Determining Calculated Peak Bow Weight

Recurve and Compound Bows. The Easton Shaft Size Chart was set up for archers using:
Variables to the "Standard" Setup:
If your equipment differs from the setup described, the variations may affect the perfomance of your bow enough to require a shaft size other than the one you would determine on the CHART. Before using the CHART, figure the effective weight of your bow (called the Calculated Peak Bow Weight) using the bow weight additions or subtractions listed below next to the "Variables" that apply to your equipment. Use this Calculated Peak Bow Weight to select your corrent arrow size on the CHART.

Variables to the "Standard" Setup:


Overdraw bows
If you are using an overdraw, make the above calculations (if any), and then multiply the Calculated Peak Bow Weight of your bow by the appropriate factor listed below.
