Both the 57 mm AGL and the A220 will have the same ability. As a concept it is now mature enough to be practical. Hard to see how the round itself will be very large if it is the same case head and OAL as the 35 mm. Performance won't be much better than the 40 mm CT with all the disadvantages of being a chaingun. Even allowing for the larger bore, MV with a 1.25 kg shell will be  900ish MPS
