Field notes

This is the 300 spine of the Gold Tip Hunter Pro (GTO), 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.302 in OD across. 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 Gold Tip GTO nock and the Gold Tip Accu-Lite insert (12.1 gr), 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 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.
