Tonight, while working up 10-rnd batches of .223, I thought may have seated a bullet in an uncharged case, so I weighed the completed loads to see if one was light. All were approx. the same weight, except one that cause the beam on scale to peg at the top. This round turned out to be a full 5gr. heavier than the others. "Odd," I thought, "what would cause that?" Anyone want to hazard a guess?

When I disassembled the round and poured the powder into the scale, in it was
walnut media! I think I audibly gasped. Apparently, enough had gathered at the bottom of the case and lodged together just enough to not be displaced by my normal routine of sifting out the media when the brass comes out of the tumbler. Now, I always visually check my charged cases (single stage loader) before seating the bullet, but still did not notice an appreciable difference in the remaining volume. Obviously, my routine will now change, but I am curious if this has happened to anyone else, and how big a deal is this? It certainly got my attention.
