I don't like wasting components. It adds a box of primers, 50 bullets, and 1/3 lb of powder to the cost of 50 pieces of new brass!
Getting to know a new rifle, not so bad, but as an ongoing thing it annoys me with my rifle anyway.
(mine has a very sloppy chamber, won't shoot well with virgin brass, to top it off I only get ~4 maybe 5 loadings before the necks split out so to even get THAT, I have to anneal, then form, THEN finally have usable brass.)
