A bit of a long question but please bear with me.
I’m specifically thinking of flight arrows here but the general principle relates to all arrows particularly wooden arrows.
I’ve come across an old film of a guy in the states called Bill Sweetland on YouTube giving a talk to a group of archers about compressed cedar arrows (https://www.youtube.com/watch?v=I8oUCNE4ulQ), very interesting to listen to. In the film, he makes mention of the weight/spine ratio being extremely important to achieve good arrow flight, and that Paul Klospeg wrote about it in the 1920’s in “his book”. I’ve got a copy of Klospeg’s book "Composite Bow" and have found the reference that Sweetland seems to refer to but there is very little information other than a general statement suggesting for any one bow there is an ideal weight of arrow.
I’ve also seen on YouTube (https://www.youtube.com/watch?v=J__NRSNv45g) a good explanation of arrow ballistics where it is explained that for every bow there should be an ideal mass weight of arrow to achieve maximum distance.
So to my question, other than being able to find a range long enough to try flight arrows (extremely difficult where I live), has there been any work done to find an ideal mass weight of arrow for a particular bow draw weight?
I’m aware of general guidance from bowyers about grains/pound of draw weight but know that is more to do with bow longevity rather than getting the most from the bow.
Any help or pointing in the right direction would be greatly appreciated, thanks.
