I cycle my brass in 50 shell lots, Ill load 50 at a time with once fired brass after they are shot I throw them in a marked bin noted as twice fired, then ill load up another 50 of once fired brass. you get the idea. then once all the brass is twice fired Ill check them for length and trim as needed I repeat this cycle untill the brass has been trimmed 4 times because afte 4 trimmings i feel theres not enough brass in the neck to keep good tension on the bullets. If the brass looked real ratty ill toss them out or if they still look good I throw them in marked bin as plinking brass which ill load for plinking and not worry about picking them up after they are fired. my pistol brass on the other hand i load them light enough that they really dont stretch and i can load them 20 to 30 times depending on the brand.after awhile they start to develope cracks and look ratty then ill load them up once more and use them as plinking ammo and not pick them up after firing.
