  1. I was just thinking about this question the other day too. I use a STI grandmaster shooing 9mm major rounds, and I'm thinking about getting another 2011 9mm limited set-up for 3-gun. I don't have a backup open gun, but could I shoot my 9mm major rounds in a 9mm limited set-up? It wouldn't have a comp, so probably throw a stiffer spring in it and hope for the best :)

  2. I looked in the seating die and that looks OK. No brass rings or dust. A belled cased does not hang up in the seating die. The crimp die is a different story. I took a picture of it because it doesn't look right. A belled case goes in the crimp die smoothly then gets hung up near the top. Some cases require quite a bit of effort on the down stroke from the crimp die. Looks like it needs some cleaning and polishing. For the guys that have polished the inside of their dies, what did you use? Thanks!

  3. I've had a Dillon 550 for 7+ years now. I use Dillon dies at all stations. I've always reloading 9mm and 40 and have never seen this problem. A couple months ago I got into reloading 45 and this magic brass dust appears. Like everyone says it looks to be too much bell binding in the crimp die. I'm belling 0.010" ( after belling the outside of the case is around 0.475") to accommodate coated Blue Bullets or Berry plated bullets. Any less bell and I begin to scrape the bullets upon seating. I've tried raising the crimp die, but then there's still some flair and they won't case gauge. Any ideas?

  4. I had those thoughts too when I started loading pistol ammo on my 550. But those thoughts quickly go away when the ammo piles up. I do think about it when I do 223 on my progressive press. I actually kind of mimic a single stage press for 223. I split the operation up over two shell plates. The first shell plate has only the sizing die. The second plate has the rest of the dies. This allows me to resize then trim, clean/deburr primer pockets, ect before continuing with the rest of the process.

  5. In my experience, the majority of double feeds are caused by a weak recoil spring combined with a weak mag spring. With a weak or under-powered recoil spring the slide comes back too fast/hard and rattles a round free. Then when the slide goes forward it grabs another round. When the mag spring is weak its easier for jar a round loose accidentally. Not sure how slowing the slide down with your thumb would play into this? Crazy.
