Field notes

This is the 340 spine of the Easton 6.5mm Bowhunter, a 6.5mm class (.246 in ID) shaft with a.246 in inside diameter. In this spine it weighs 9.3 grains per inch and measures.298 in OD across. A 340 spine sits at the mid range, the most common hunting-weight compound band.

Because the bore is.246 in, it takes the 6.5mm Microlite nock (8 gr) and the 6.5mm insert (23 gr, 5/16 field points), and it threads to the 8-32. Those do not change with spine; only the GPI and outside diameter move across the table.

Spine is a starting point, not a guarantee: a 340 from one brand can differ from another. Read your exact draw weight and arrow length on the maker chart or bare-shaft test before cutting a dozen, and keep the finished arrow above the 5-grains-per-pound floor.
