I was issued a M-2 at one time in service and I got to shoot plenty of rounds with it.We quilified with it up to 300 yds which wasn' t bad with those big bullseyes.If you got one with a good barrel they shot very well at that distance.I don' t remember the fire rate but it was susposed to be faster than a 30 cal machine gun.
Once we were on the firing range,think there was about 30 of us,a rabbit came hopping slowly accross about a 100 yds out every one fliped them on auto and that rabbit made it all the way accross without a scratch,now that was some great shooting.
