9mm cases will not chamber
Quote from Reloader on August 19, 2012, 4:48 amUsing a Dillion 550 with Dillion dies. Out of about 1000 rounds reloaded, 45 9mm rounds have a bulge at the base of the brass casing. The round will not chamber due to being oversized . This is used brass from different makers. I would understand if all 1k rounds come out the same, that my resizing die was not set up correct. This did not happen only about 45 rounds had a bulge or was not resized to a proper size.
I am running these rounds in a Glock 19 and a Sig Sauer 938. I did as advised by Dilion, check a round for proper breach size about every 50-80 rounds for proper chamber fit using the Glock 19 barrel.Any advice this issue?
Thanks in advance,

Pull the bullets out of a few of the bulged cases, resize them only, then see if the cases freely drop completely into the chamber.
Some firearm chamber do not sufficiently support the bottom of the case during firing, which allows the case to expand beyond the point where the size die can resize them. Once the webbing at the bottom of the case expands, a conventional resizing die cannot restore them.

Quote from Reloader on September 7, 2012, 9:33 pmCheck your crimp, too heavy and it will bulge the case, also too much belling can do the same. You have to remember, some of that brass could be stressed from multiple loadings, moisture, oversize chambers. The sizing die will not reach to the extractor groove of the case.....to do that the mouth of the die would be too tight to work properly in a progressive press. Try using roll sized brass....but check the other factors I first mentioned. I have reloaded a lot of 9's on a 550 with Dillon dies...never had a problem. We are dealing in thousands of inches here so dilligence is the way to go!

Quote from Reloader on March 6, 2013, 11:21 pmThis is a common problem with 9mm. I often have brass that will not resize fully and will jam in the chamber. There are two solutions. 1) test every round in a case gage and dispose of the oversized rounds. 2) Buy a Case Master Jr ($325) and it will push the brass all the way through to fully resize back to factory specs. If the bottom of the case is blow out, you will not fully resize it using standard dies no matter how low you set it. I test EVERY round with a Dillon case gage. If it fits in the gage, it will fit in your gun. If you reload a lot, buy a Case Master Jr.

Quote from Reloader on March 14, 2013, 10:55 pmI have that SAME problem on my RL1050! Some call it the "Glock bulge" from brass that's been fired through a Glock. Others say it's because it's been fired through an UZI. Rounds that don't chamber in my Lugers, Walther P38 or Beretta 92F will still chamber in my UZI. But yes, I check every cartridge with a Midway case gage before I go to the range.

Quote from Reloader on March 19, 2013, 5:09 amI too have a problem with 9mm not chambering. But I've noticed that the bullet is not seating straight in the case. There is a bulge around the bullet that is more pronounced on one side. I take the barrel out of my gun and assure each round will drop all the way in and fall out unaided.

Quote from Reloader on March 27, 2013, 8:21 pmI had this same problem also. You can simply remove the decap pin assembly from your size die and run the bulged cases through it. Adjust the die so it barely clears the shell plate or shell holder in a single stage press.

So far, I have had no problems with my Dillon 9mm dies sizing cases shot in a Glock. All pass the chamber gage test and shoot just fine.

Quote from Reloader on July 12, 2013, 9:20 pmI am seeing the same thing on my Dillon 550B with 9mm brass. I have been checking all my 9mm reloads with a Dillon case gage (yes I'm anal). I find one in about every hundred or so rounds that are out of spec according to the case gage. My sizing die is adjusted properly as per the instructions and I have experienced no feed issues with either of my 9mm's. It does not seem specific to any brand brass. I am shooting a browning Hi-Power and a Taurus Slim.
