Where will it stop. Gun jamming falls into the same category as gun freezing, and overheating. I dont have any literature on the subject, but heard Chuck yeager say in an interview that , the .50's would burn the barrels after about 3 consecutive seconds of firing.
I personally, wouldnt mind any of the realisms being introduced,
but the "I PAY MY 15 DOLLARS A MONTH AND IF I WANT TO SHOOT MY GUNS, THEY BETTER GORD DAMMED WELL BE READY TO GO, OR ELSE I'LL QUIT AND CANCEL MY ACCOUNT" crowd carries a lot of wieght in the MA.
