Clear-able jams or unclear-able jams?
In other words, if you jam it in flight are you done shooting until you re-plane?
I'll take unclear-able jams if pilot induced by shooting at over 2.5 G's or so.
As far as "continuous fire jams" I'd say no, base on anecdotal evidence. My father used to strafe Japanese airfields in a B-25C strafer nose. He says policy was to hold the trigger down all the way across the field. 15-30 seconds of continous fire. Rarely a jam. However, usually warped barrels by the end of the run and rounds "cooking off" after you released the trigger. (Note: the barrels were not necessarily "ruined". Some were replaced after a mission some were OK after they cooled out.
Anyway, do it with the unclear-able 2.5G limit.
I want to see how long it takes for the screams to "change it back, change it back!" to start.
