Why? Because factory ammo is cheaper and more accurate?
I'm not who you responded to but I'll add that i'm in a similar position. I have enough powder and components to get me through. I'll load when I need to and buy for now. There's good quality ammo available at reasonable (today's) prices. If I factor in my time, the ammo is the better deal. For someone shooting a common cartridge that has to seek out components, ammo is a great deal. If you want reloading quality ammo, you can pay for it and get it.
