The size of the pellets can vary depending on when the extruders at the factory were last cleaned. Watch carefully in the future and you will see a fair amount of variation of the AM600 over the long term. It would think there are ways the operator of the extruder can slightly change the size of the final size of the pellet. The main complaint that I have with Purina Aquamax feeds is their quality control is sort of 'loose' regarding production of the larger sizes of Aquamax.
