Field notes

This is the 400 spine of the Carbon Express Maxima Sable RZ, a dual-spine (.244 in ID) shaft with a.244 in inside diameter. In this spine it weighs 7.5 grains per inch and measures.290 in OD across. A 400 spine sits at the mid range, the most common hunting-weight compound band.

Because the bore is.244 in, it takes the CX Launchpad.244 precision nock (9.9 gr) and the CX insert (11 gr, spine-specific), and it threads to the 19/64 field points. 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.
