The magazine for the Messerschmitt Bf-109F-2 that was the first used the belt fed
heavy machine gun Mauser MG-151/15 allowed a belt of 200 round of the 15x96 ammo.
Then in the version F-4 with the introduction of the Mauser Mg-151/20 20 mm canon the capacity of the magazine descend slightly to 180 rounds, although very often even less ammo such as 150 round where loaded.
In the late G-6s/G-10/K-4 versions was also available the Reihnmetall MK-108 30 mm, for bomber hunting business, the Messers magazine only could hold 65 rounds, just enough for a 6,2 second burst of this heavy canon.
