I personally only run my 9 major and 9 minor brass once and leave it on the ground for others so if you picked up mine it would probably be fine because I buy once fired brass from police ranges so it’s most likely only been loaded once. Random range pickup brass could have been loaded multiple times and you could get a lot of split cases, bulges in the base of the case from somewhat unsupported chambers and loose primer pockets from hot loads. Once fired 9 brass is cheap to buy. Saves your back and time on scrounging like a chicken at the range after a match or practice session.
