I have a Sig m716 that I really want to shoot, and I really want to take advantage of the semi-auto feature. Problem is, all the ranges I have looked at wont allow .308 ammo (I guess I could shoot 7.62 if I have to, but I prefer higher grain .308), and/or they will only allow single load shots with that rifle. Anyone know of anywhere I can actually fire this thing the way it was intended to be fired? Thanks in advance.
