As comparison the Finnish Fokker D.XXI pilots quickly noted that the .303cal guns were not enough to reliably kill a well armored bomber nor a fighter with good armor plate behind pilot. For example in many occasions the I-16 had been peppered by all 4 x .303cal but the plane puttered on as the rear armor behind pilot stopped the bullets. Same applied to Soviet bombers like DB-3 that had tough armoring in the fuselage, pilots had to aim very carefully to kill the engines so the plane fell. Fokker D.XXI had 2200rds of ammo and many times most of it was used. So you can imagine the joy when Brewsters with 4 x .50cal came and shredded the opposition compared to Fokkers. Bf109G-2 and G-6 later on brought the cannon into play and pilots all stated that the 20mm was more than enough to kill a fighter easily and bombers with short bursts.
