RE: Finished arrow weights- How close is enough?
Range,
If I am building arrows for target I try to get all arrows within a grain finished weight. To do this I weigh all components, sort them out to get as close as I can through matching parts. Then I fletch and re-weigh, then make the final adjustments with tip weight. I often buy 3 dozen tips, adaptors, and other components to get a dozen closely matched parts. It may require making weight adjustments to the components prior to assembly. I usually will get within a few grains before adjusting tip weight. Remember to not get too crazy with your glue, it can cause some weight variances.
Aim Hard!
