You will most likely be renting the shooting lane by the hour or half hour. To make the most of your time, have your range bag well organized so you can reload quickly and safely. Make sure you have eye protection and I recommend electronic muffs so you can hear any commands from the range boss. (under $30 at Menards)
Read and obey the range rules. You might want to bring along a big piece of cardboard as a back stop for your paper target. Some ranges provide this free and others do not. If you have to pay by the hour or half hour some ranges will allow you to preload your mags before your time starts. If not, or you have a limited number of mags, buy the Uplula magazine loader if you don't already have one. It will allow you to load your magazines much more quickly.
Here's a suggestion for your next trip. Most weeks, I hit the range twice a week and run through 300-500 rounds each trip. I reload my ammo and my cost per round is as low as I can make it and still use top quality materials. I turn the silhouette targets around and stick Birchwood 1" orange stickon targets to the backside - 4 rows of 3 targets, top to bottom. The front desk always gives me two silhouette targets (they're free) and that gives me 24 bulls to shoot at. I go back and ask for more silhouette targets (still free) when those are shot up and if I'm not shot out. Shooting at silhouette targets isn't much fun for me so I put the stickies on. My eyes are 63 years old and the white background on the back vs. putting them on the front of the target helps me see the hits and read what I'm doing right or wrong. I buy the Birchwood stickies in bulk from Amazon Prime - great price, free shipping, and I get them in a day or two.
Not sure how many ranges are in your area, but check out each of them. You will develop a "favorite". One has better lighting. One is less expensive. One has better staff. One "feels" safer (ballistic panels between the lanes vs. pegboard between the lanes and bullet holes in the ceiling, etc.).
