I'm inclined to think that the closed bolt smgs like the HK MP5 or UMP are more accurate than the open bolt since the "lurch" of the open bolt gun can throw you off slightly. Accuracy is a factor which depends on the operator and the condition of the firearm. Remember that sustained full auto fire wears out a barrel faster than anything else (besides enthusiastic scrubbing with a sectionalized steel rod and stainless steel brush). Furthest we ever fired in practice was at 75 yards and with iron sights, we went for the chest. We have an old thread here where some folks went beyond 100 yards.
