I normally load all my firearms using same-headstamp cases, but I got tired of this with my 9mm. Seemed like every time I took 50 rounds to the range I would come back with lots more 50-150 cases, but never could find every one of the original 50 cases. So I finally gave up trying for matched headstamp sets. BUT-- I still wanted to cycle through the brass, not using the same cases every time. So, here's my new project. I took a small pet feeder and mounted a piece of 4" PVC pipe on the top. I take all that range brass, including my own empties, decap, prep for reloading (NO primers) and dump them in the top. When I want to load I just pull them out the bottom. It sits conveniently on the shelf by my reloading station and doesn't take much shelf space at all. It holds about 2500 9mm cases, and feeds nice and smooth.
