For this fps you should use the 0.25 gram, 0.28g or even the 0.30gram.

0.20g (300~350 fps)
0.25g (350~400 fps)
0.28g (380~420 fps)
0.30g (400~500 fps)

The heavier the bb the more accuracy you will get. Since all the Matrix bb are 6mm in size, all of them will work, the heavier the bb the less the muzzle velocity (due to the heavier weight), but due to the increased accuracy and alteration of wind friction result, find the best result with your current bucking / hopup adjustment and stick with it.

I would recommend 0.25g or 0.28g Matrix for this rifle.
