Carbon Arrows

Carbon arrows for bow hunting

Carbon shaft dominates the modern hunt arrow market. Alloy (aluminium) shafts still ship, and the Full Metal Jacket family layers aluminium over carbon for penetration mass. This guide covers the pure-carbon shaft category: what spine, GPI, straightness and diameter mean in practice, and which brands earn a recommendation.

Spine

300 / 340 / 400 / 500

Match to draw weight and arrow length.

GPI

6.5 – 12.0

Grains per inch. Heavier shaft = higher FOC potential.

Straightness

.001 / .003 / .006

Inch of runout end to end. .001 is target-grade.

Diameter

.204 / .246 / .300

Micro shafts penetrate deeper, catch less wind.

Carbon vs alloy vs FMJ

Pure carbon (Easton Axis, Gold Tip Hunter, Victory VForce): lightest, cheapest per dozen, forgiving. FMJ (Full Metal Jacket, aluminium jacket over carbon core): heaviest for FOC-first builds, penetrates deepest, costs the most. Alloy (Easton XX78): traditional-archery choice, rarely used for modern compound hunt.

Arrows

Every carbon shaft, honestly compared

Spine, GPI, straightness, and diameter are the four numbers that decide whether an arrow flies. We tune each shaft on the same 65 lb Hoyt RX-7, walk-back tune to a bare shaft, and paper-tune every dozen we recommend.
