6 shot neutral does not mean 6, 6, 6, 6 it means a course of fire that can be completed in the same amount of reloads. You can have a 16 round course and if set up properly it will take 3 reloads with both 8 shot and 6 shot. Example would be 7, 4 and 5 would force 3 reloads with an 8 and can be shot with a 6 with 3 reloads.
