Altra .246 Centrum Limited – Kauffman Custom Build

Standard-Diameter Toughness. Bulletproof Construction. Dependable Field-Grade Accuracy.

Built for archers who want a workhorse arrow that can take severe abuse on the 3D course, in the field, or at target practice, the Altra .246 Centrum Limited offers rugged durability without breaking the bank. Designed on a standard 6.5mm (.246" ID) carbon frame, this shaft combines easy component setup, high hoop strength, and dependable performance across a wide range of draw weights.

Featuring Altra's seamless NO SPINE™ Technology, every shaft is constructed without a structural seam, ensuring consistent 360-degree dynamic flex regardless of how your nocks or broadheads are rotated. Rated to a reliable ±.003" straightness tolerance, the Limited series brings hard-hitting, repeatable flight to everyday bowhunters and high-volume shooters.

At Kauffman Custom Archery, we treat every shaft with the exact same precision bench prep as our top-tier match arrows—ensuring your setup leaves the shop perfectly squared, indexed, and ready to fly true.

The Kauffman Custom Studio Difference

Even dependable field-grade carbon requires zero-compromise bench work to eliminate broadhead wobble and deliver tight groupings downrange:

• 360° Roller Spine Indexing: We spin-test every shaft on precision dial-indicator rollers to locate optimum dynamic stiffness and index nocks for identical flex out of your bow.

• Dual-End Diamond Truing: Carbon ends are precision-trimmed and squared using high-speed diamond wheels, creating a dead-flat 90-degree seating face for standard inserts and nocks to eliminate broadhead runout.

• Chemical Degreasing & Custom Hand Fletching: Shafts undergo complete solvent cleaning before receiving heavy-duty custom wraps and hand-fletched high-profile vanes (Q2i Rapt-X or AAE Max Stealth) for maximum broadhead control.

• Grain-Matched Dozen Sets: Your complete set is hand-sorted and grain-matched across the batch to keep your point-of-impact identical shot after shot.
