Another possible candidate is the AIFV. In the dutch OB (nr 28) known as the YPR-765 PRI (unit 176 and 056), in the belgian OB (nr 27) as the AIFV-B (unit 064) and in the Turkish OB (nr 32) as the ZMA-AIFV (unit 176).
The are all basically the same vehicle with the 25mm KBA autocannon. The dutch have 9 HE and 8 AP, the belgians have 7 HE and 6 AP and the turks have 7 HE and 8 AP.
According to:
http://www.answers.com/aifv
the ammo load is 180 rounds ready ammo and 144 in reserve. That would mean that the current ammo load would reflect a 20+ round burst per shot.
Also note that the vehicles have different carrying capacities in the three OB's, 10 for the turks, 9 for the dutch (unit 056 has capacity 5), 8 for the belgians.

Edit; looks like the turks have a different version after all with a higher carrying capacity. I'll take that issue to another thread on the AIFV.
