semp, tell them the secret.
Spit8 .303, you need to be shooting at a slight angle so you magic BB the pilot through the side of the canopy. The wide mounting of the four .303 in the spit8 creates a large dispersion area just past convergence. If you stagger their convergence like (B1 250), (B2 275), you will have a dispersion cloud for runway vulching that almost always gives you pilot kills. Then if they do get up slow and turning, you will snap shoot a BB into the canopy. You can kill bombers that way by HOing at close range into the pilot side windscreen. Either when they spawn, or are trolling around at ground level for fighter kills. I watched semp a long time ago getting his kills in the spit8. Who do you think taught me heheheheh.
Offline when you use the .303 from inside of 400, your rounds are always dropping into the side of the canopy due to the lazy turning circle and because of the slow speeds, you can concentrate your rounds. Depending on the plane, some go down quickly, some don't. You can get armor descriptions for the rear 180 protection of the pilot. Some were better than others. HiTech seems to model that.
After BoB, both sides started adding more armor to fighters. With a .303, then you needed to kill the pilot or, punch little holes all over the place hoping to damage enough hoses, electrical conduit, air bottles and cables to force the plane down or RTB.
With the spit8 I often get 2 kills after the 20mm's are out. Usually during a 45-90 deflection shot raking the canopy or a 6 shot 15-30 degree angle off into the canopy. Or HOing a bomber's cockpit. Otherwise just assist city against all of the late war rides.
