I once bought a SDB in an estate. It was set up in 9mm. I sold it because I didn't shoot 9mm at the time. I wish I had kept it now...even though I am not loading 9mm at this time. It is not economically worthwhile to load 9mm for me. Not much room on a SDB but they have a good reputation. I also don't use a Rockchucker...but I do use the older A2.LOL!
