taking too many guns to the indoor range at the time ?

I have a bunch of unfired guns that I need to take and test out, like 7, so it will be a pain to drag the 5 pistols and 2 rifles in and shoot all of them. What always happens is I end up taking one of my favorites along and mostly shoot that one, and barely put more than a mag through the others.

I just hope that I'm not nagged that I'm shooting too fast like I was a couple of years ago when I tested a bunch of guns. I had to be at work a couple of hours after I got to the range, and the rangemaster (His nickname was "Fuhrer" kept interrupting me, saying I was shooting too fast. I tried and tried to explain I didn't care about accuracy, I just wanted to see if they all shot reliably. By the time I was done shooting, instead of just leaving, I complained to the owner about him nagging me, and told him as long as I wasn't breaking any safety rules, I wanted him to leave me alone. I haven't been back there, but it's in a really convenient location, so I might give them another chance.

Only time I ever go to a indoor range is when I buy a surplus gun and want to make sure it’s on paper before I go to the good range with electronic target systems. I hate shooting indoors
