Between the two I estimate a balance of cost and performance. I am wondering if there is an appreciable difference cost wise reloading the two. From my reading, the Hornet uses about 1/2 the powder, bullet cost is similar, the .223 will get more loads per case with proper care due to brass thickness. The latter is referring to max loads in both and not losing any to splits or crushed necks (Hornets thinner brass wears faster?). I know technique can prevent a lot of problems with the Hornet, but side by side, could the cost of replacing brass vs powder usage make these two about equal to reload?

I am trying to decide on which one for an economical 200 yard max groundhog rifle that doubles as a great plinker.
