Frequently Asked Questions

What is the 6mm WOA cartridge?

The 6mm WOA is an AR-15 wildcat cartridge developed by White Oak Armament. It's essentially a 6.8 SPC case necked down to a 6mm projectile, designed to offer improved ballistic performance within the AR-15 platform's magazine constraints.

What are the best bullet weights for the 6mm WOA?

Testing indicates that the 6mm WOA cartridge performs optimally with bullet weights in the 87 to 95 grain range. Heavier bullets like 103gr and 107gr can be stabilized but may present challenges with magazine length and jump to the lands.

How does the 6mm WOA compare to other 6mm AR-15 cartridges?

Compared to cartridges like the 6mm AR (potentially 243 LBC or 6mm Grendel), the 6mm WOA might have slightly less internal case volume, potentially limiting the seating of the very heaviest 6mm bullets at magazine length. However, it offers a good balance for many bullet weights.

What are the reloading considerations for the 6mm WOA?

Reloading for the 6mm WOA is described as very easy, with straightforward brass forming. Common powders like Vitavori N550, Reloader 17, and AR Comp are effective. Careful attention to overall cartridge length is crucial for magazine feeding.

Where can I get a 6mm WOA barrel?

Currently, 6mm WOA barrels are not listed on White Oak Armament's website. Interested individuals should contact White Oak Armament directly, as they are willing to custom-make barrels in various configurations.
