Excalibur Matrix Crossbow String Replacement - Reduced Creep & More

In this review the Excalibur Matrix crossbow string is evaluated for serious hunters and owners of Excalibur Matrix and Bulldog series crossbows. The bottom line: it is a straightforward replacement string built from BCY DynaFlight 97 that aims to reduce string creep and eke out a bit more speed while offering a longer-lived center serving; owners who want reliable performance with minimal tuning will appreciate it.

Key Features

• DynaFlight 97 material: provides a high strength-to-weight ratio so the string helps maintain speed and resists stretch over time.
• Proprietary center serving: extends serving life under heavy use and reduces the need for frequent maintenance.
• Reduced creep: the construction is intended to keep the string length more stable so your tuning holds up shot after shot.
• Increased speed: the low-stretch fibers contribute to slightly higher arrow velocity compared with older or worn strings.
• Series compatibility: made to fit Matrix and Bulldog series crossbows including Matrix 405, 380, 355, 310 and Bulldog 400, 380, 440, 330.

Who It's For

This replacement string is for owners of Excalibur Matrix and Bulldog series crossbows who want a direct-fit upgrade using modern BCY material and a tougher center serving. It suits hunters and regular range shooters who prefer to swap in a fresh string that reduces the amount of tuning and servicing required between seasons.

It is not for users of non-Matrix or non-Bulldog models, or for someone expecting a universal string that fits every Excalibur variant; double-check exact model compatibility before purchase. Those wanting a custom-length or nonstandard string should consult a pro rather than using this off-the-shelf replacement.

Pros

• Quality BCY DynaFlight 97 material improves speed and resists creep compared with older strings.

Cons

• Fit reports are mixed for a few specific models, so some users may need to verify fit for certain special editions.
