Early this morning I intercepted a formation of B-29s with a Me-163.
On the first or second pass my left cannon was damaged and I had around 100 rounds left.
After 5 or so more passes I was out of ammo and had to RTB, and I noticed my ammo count was at 0.
I wasn't paying close enough attention to remember if both guns where firing after the 1 gun was damaged, and unfortunately I don't have it recorded.
