Field notes

This is the 400 spine of the Gold Tip Kinetic Pierce Platinum, a micro (.166 in ID) shaft with a.166 in inside diameter. In this spine it weighs 7.6 grains per inch and measures.229 in OD across. A 400 spine sits at the mid range, the most common hunting-weight compound band.

Because the bore is.166 in, it takes the Gold Tip GTO nock (5.3 gr) and the Gold Tip ballistic insert system (43.5 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 400 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.
