I reloaded to get my favored hunting load that was often not available here. I shot crows in the off season with the same load. Going through 4-5 cases(500 rd cases) made reloading worth it.

With the current cost of componets, I'm not sure you can save unless you shoot an awful lot. Do the math.

Aside: Noticed that Wal-mart had Winchester shells that exactly matched my favorite load, on the shelf for $11.75.
