Federal Premium 6.5 Creedmoor 130 Grain Swift Scirocco II

The bonded-core construction of the Scirocco II is specifically engineered to resist core-jacket separation on impact, which is the primary mechanism behind weight loss in conventional cup-and-core designs. Swift’s published component data for this bullet reports weight retention above 95% across a range of impact velocities in controlled testing. In practical hunting terms, this means the bullet is more likely to stay together on angled shots or when encountering heavy bone before reaching vital tissue. Non-bonded bullets at comparable velocities can shed 30–50% of their weight under those conditions. This retention characteristic is a core reason hunters select this load for situations where shot angle cannot be controlled.

Both are legitimate premium hunting loads for whitetail, but they reflect different design priorities. The ELD-X at 143 gr carries a significantly higher G1 BC (0.625 vs. approximately 0.520 for the Scirocco II), which translates to less wind drift and drop at extended range. The Scirocco II at 130 gr offers a slightly flatter trajectory at moderate distances due to its higher muzzle velocity from a lighter bullet. The ELD-X uses Hornady’s InterLock-style mechanically bonded design, while the Scirocco II uses a chemical bonding process — both are credible for controlled expansion. Price and BC favor the ELD-X for most hunters; the Scirocco II appeals to those with a specific preference for the Swift bullet’s terminal behavior or Federal’s brass quality.

The 6.5 Creedmoor cartridge and the Scirocco II bullet are technically capable of ethical terminal performance beyond 400 yards, provided the shooter has confirmed their rifle’s actual muzzle velocity, a verified zero, and the ability to calculate or measure environmental corrections at that distance. The bullet retains adequate energy for deer-class game well past 500 yards under favorable conditions. However, the practical limiting factor is shooter capability and field conditions — wind drift at 400+ yards on a hunting shot is substantial and difficult to assess in the field. This load is not a poor choice for longer shots; it simply requires the same disciplined preparation any extended-range hunting shot demands, regardless of cartridge.

A 1:8 twist barrel is well-suited to stabilize 130 gr 6.5mm projectiles. The Scirocco II at 130 gr has a moderate length-to-diameter ratio that stabilizes reliably in both the common 1:8 and 1:9 twist rates found in factory 6.5 Creedmoor rifles. Stability issues with this bullet weight and twist combination would be unusual. If your rifle was manufactured for the 6.5 Creedmoor cartridge by a reputable manufacturer, twist rate is unlikely to be a limiting factor with this load.

This is a known gap in Federal Premium’s product data for certain Swift Scirocco II offerings. Federal publishes full ballistic tables for many of its loads but does not consistently do so across all SKUs in every caliber. The absence of published velocity data does not indicate a performance deficiency — it reflects an inconsistency in how manufacturers populate retail product pages versus technical data sheets. Shooters who require confirmed velocity data for ballistic solver inputs should chronograph this load from their specific barrel length, as published figures would represent a 24″ test barrel result that may not match a 20″ or 22″ hunting rifle. This site will update the spec table if Federal publishes official data.
