The 0,43gr and 0,45gr airsoft bb's are unfortunately no longer allowed within NL but can still be used in Belgium and other neighbouring countries.
The NABV has set a limit on the use of heavyweight bb's which is set at the maximum weight of 0,40gr. This rule started at the moment we stopped the FPS measurements and switched to Joule measurements.
In Belgium and other neighbouring countries FPS measurements are still used and 0,43 and 0,45gr bb's are still allowed.
