Depending on how you are shooting. If you are an SKS jackass spraying the range with uncontrolled lead and hot brass I will kick you out. If you are shooting in a slow controlled maner with the rounds impacting the berms and have a good working/safety knowledge of the firearm I have no problem with you shooting with more than one round in the mag. And if you are wondering I am the RSO for the Mission Rifle Range.
I do agree that there are times that I shake my head. Just the other day some guy showed up with another buddy and his wife and they just started blasting away. After getting swept with the muzzle for the second time I asked him nicely to slow down with the shooting and load one round at a time...after protesting I asked him when he got the rifle, a week ago
