Easton 5mm FMJ Max – Kauffman Custom Build

FMJ Penetration Power. Lighter Carbon Core for Higher Velocity and FOC.

Engineered for bowhunters who want the bone-crushing kinetic energy and easy target pull of a Full Metal Jacket without sacrificing arrow speed, the Easton 5mm FMJ Max delivers a lighter-weight aluminum-carbon composite platform. Fusing a seamless Acu-Carbon core with a 7075-alloy aluminum jacket in a rugged hard-anodized OD Green diamond-plate finish, the FMJ Max yields lower GPI weights than traditional FMJs. This weight reduction gives you total build versatility: run a flatter, faster trajectory into western drainages, or pack heavy brass up front for extreme Front-of-Center (FOC) stability.

At Kauffman Custom Archery, we take this lighter FMJ setup and apply our dedicated studio bench workflow to deliver spin-tested, broadhead-ready precision out of your bow.

The Kauffman Custom Studio Difference

Lighter GPI composite shafts paired with high-FOC builds require exact shop prep to prevent arrow-to-arrow point-of-impact shifts at long distance:

  • Static Spine Testing & Indexing: Every shaft is statically tested on our precision spine gauge to identify its principal stiff plane, ensuring uniform shaft flex and dynamic reaction out of the bow.

  • Dual-End Diamond Squaring: Both point and nock ends are trimmed and precision-squared using diamond wheels, creating a 90-degree flush seat for HIT inserts, steel half-outs, and nocks.

  • Custom Hand Fletching: Shafts are degreased, wrapped with heavy-duty Onestringer custom wraps, and hand-fletched with high-profile vanes (Q2i Rapt-X or AAE Max Stealth) for maximum broadhead steering.

  • Grain & Balance Sorting: Your entire set is weight-sorted across the pack to maintain tight grain tolerances and repeatable point-of-impact.
