I have been reloading 223 ammo this past summer but just starting with pistol ammo. I seem to recall reading alot of posts that people say you can reload 9mm almost as many times as you want but with 40 it seems like people want to limit how many times its reloaded. I can understand being able to reload say 45acp more than both of them since its much lower pressure but the listed pressures for 9mm and 40 seem similar. Is it able to be reloaded less due to case size or something I'm missing? Also is more to do with high power loads versus more moderate practice rounds. I have some once fired brass that I've been saving from factory ammo I've shot and also range pickup brass and trying to figure out if I should keep track and discard the brass after a few reloads or just inspect it and keep loading it if it looks good, I will be shooting weaker loads as they will just be for practice and not going for max loads. The location I shoot is out in the woods and is a great area for keeping track of brass, I dont think I've lost a piece of brass there all summer as its a nice gravel area. I know some have said you would lose brass before you reload it too much but since I rarely lose any I'm not sure that will be my case. I tend to overthink things and trying to decide if I should keep track of each firing or just keep tossing it all together as long as its still in good shape, would make it easier for cleaning,loading, organizing ect as long as its just for reduced loads, but I also dont want to overuse the brass. I plan to reload both 9mm and 40S&W so some input would be appreciated.
