So don't hate me but I usually don't clean everything after each trip to the range, since I bring a lot of different things to try we typically only shoot about 40-50 rounds through each gun per session and I don't have time to clean 6 or 7 guns. I do keep tabs on the overall number of rounds fired and try to clean at about 1K rounds. I don't use any corrosive ammo ever so that's not a concern. Does that seem reasonable to you? My line of thinking is if in military applications it can be shot for hundreds and hundreds of rounds that should be sufficient.
