I can see both sides of this. As a reloader, I don't need to buy factory ammo IF I have the components to make it myself. But sometimes I don't have the components.
I decided to start loading 7.62x39 a couple months ago and am currently hunting for components. I have found LRP's (which I didn't have since I've never needed them before), powder, and bullets. I have also found some factory 123gr FMJ's , which my rifle likes, and will also give me once fired brass for reloading. I couldn't find brass when I made the decision to load for this rifle, but factory ammo was available. I can find brass now, but have no need for it (due to buying factory) and will likely wait for prices to stabilize/drop before stocking up.
