Lots of great advice here. I hadn't really thought about the vacuum before, but will use a broom from now on. Here's my own cautionary tale that I haven't seen here yet. I had a beautiful new Cooper in .257 AI. One day I pulled the trigger on what I thought was a normal load. Click, no bang, empty casing when I opened the bolt, so I put a light down the barrel and the bullet was jammed just ahead of the chamber. As near as I can figure, I missed putting powder in that one and the primer drove it into the barrel. Despite what I read on the web, that bullet would not come out, even after I bent a brass rod with a hammer to drive it back. I ended up sending it to Cooper who did their usual class act thing and rebarrelled the gun for free. Lesson learned - Now I weigh each finished loaded round of every batch. If it's more than a grain off, it gets recycled. Like the carpenter says "Measure twice, cut once. This routine also will catch double charges (from being distracted while loading) and is much more reliable than a flashlight. You do need a good electronic scale, not cheap, but I can check 50 rounds in a very few minutes and I then feel much better.
