Indoor: I sweep my area & any loose brass forward before I start. I pick up after each mag, most times I load 5-10 for precision or cadence drills. Transition, Reload type drills I'm only loading a few so its easy to keep track. More about quality than quantity I'm throwing down range. Come back with 95+% of my brass. I would never take any range brass, not just the principle of it: not mine, but dont know the history or the casing, not willing to waste time to sort bad from good or have split cases come on early.
Outdoor: I do the same, clean my area and the area I know empties will go. Movement drills are the same. Time consuming but I get my brass & have got use it.
Both help me leave the range cleaner than I found it.
My buddy that shoots at an outdoor range marks his headstamp with a colored sharpie, but that takes forever. Think he pays his little elves with sweets to help him.
