Shaft diameter
The shaft diameter varies according to its intended use. To give an example for 3D one will typically look for a larger diameter arrow to improve one’s chances of touching a line and in so doing get the higher score. The same can be said for indoor archery although there are limits imposed dependent on which indoor one shoots. World Archery dictates a diameter no larger than 23/64” or “23” on its 3 spot targets, whereas IFAA has no limits and up to the larger 27/64” can be used. With Indoor there is obviously no wind effect but a windy day with a fat 3D arrow can be problematic especially on the longer distances.
Thinner arrows are used for disciplines requiring high numbers of arrows in a tight space e.g. field, 720 and Indoor single spot. A smaller shaft diameter also has benefits in wind as there is less surface area to push around. In the previous point on fletch size and together with shaft diameter these factors will determine the amount of wind drift.
Nocks
Nocks are also a personalized item, what colour shape etc. That being said most arrow manufacturers supply their arrows already “nocked”. This is according to their quality standards and what would work best standard and cost wise. Nocks however can be changed and accessories added such as uni-bushings and pin nocks to both better performance and durability of the arrow. Target archers who are packing arrows in tight groups opt for pin nocks as this saves the arrow shaft from damage on costly arrows.
The ideal fit of the nock on the serving can be done by facing the bow towards the ground and plucking the string like a guitar. The nock should pop off the string, if not the nock is too tight, if the arrow just falls off the nock too loose. Always check your nocks where there are close groupings shot because arrows coming into contact with each other can crack nocks which could break when you next shoot them resulting in a dryfire.
Points
Points are available in various shapes and weights and dependent on the use of the arrow this will determine what point is used. Practice or field points are generally used by most archers other than when they are hunting or using target specific arrows. Points can be attached either by using inserts or glue-ins.
