FX recognizes that there are other equally comparable precision slug manufacturers and they plan to develop slug liners to add to the series. They also plan to add additional caliber options.
The company also says that lighter slugs will shoot better out of shorter 500mm barrels. Heavier boat tail shaped slugs may not fit in the current magazine design and will need to be single loaded. For optimum accuracy, only use swaged slugs sized correctly to the bore diameter.
