I've seen guys that have tens of thousands of primers and supplies just for reloading. My reloading supplies is anemic in comparison. As for ammunition, depending on the gun I have anywhere from a handful to thousands of rounds. With the current scare I haven't done much shooting, it almost feels like we're in a bad harvest year. It would be nice to have 10,000 rounds of 9mm but I don't even think I'd get through it all in a lifetime. Granted if there were more shooting events in my area I may. But for pure recreational shooting I have never felt I didn't have enough. I realize enough and more are obvious answers. But what is considered practical or safe?
