I have a handful of premium, high priced commercial "self defense" rounds, all with a dent in the primer. That is, I pulled the trigger and nothing happened. I keep them to display them in classes and explain why they're the most dangerous rounds in the world, and that they represent the one thing self defense ammo cannot do.
So I don't trust anyone else to load my self defense rounds anymore. Therefore, loading my own, I have thousands of rounds for each caliber, and each has the softest primer on the market. A lot of it is loaded, say a thousand or so for each caliber, and I have the components to load several thousand more. I have an ammo box full of loaded 1911 magazines and twenty loaded 30 round mags for the AR. I don't think I actually have ten thousand rounds for any caliber, but with .45 ACP it's possible. I buy Montana Gold JHP by the case, which is just short of 3,000 rounds, and that lets me carry what I train with. Add in LRN, LSWC, JSWC and FMJ, and I suppose it could hit ten thousand.
There are a couple exceptions in my bullets, I also have thousands of both lead and jacketed SWC for .45 ACP and I have some target stuff for my bolt .223 that I'm not sure I'd call self defense ammo, although of course, if it came down to it and that's all I had, I'm sure it would work. But the AR doesn't really like bolt ammo, and vice a versa, and I'd rather have JHP for the .45 than either flavor of SWC, but that's all sort of nit-picking, I guess.
