Field notes

This is the 300 spine of the Easton 6.5mm Match Grade, a 6.5mm class (.246 in ID) shaft with a.246 in inside diameter. In this spine it weighs 9.5 grains per inch. A 300 spine sits at the stiff end of the range, for heavy compound draws and heavier points.

Because the bore is.246 in, it takes the 6.5mm Microlite nock (8 gr) and the Easton 6.5mm insert (25 gr), and it threads to the 8-32. Those do not change with spine; only the GPI move across the table.

Spine is a starting point, not a guarantee: a 300 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.
