SERVED_USMC Posted March 6, 2012 Share Posted March 6, 2012 Just swapped over everything in the 650 to start on some 9MM. Dies are brand new Dillon carbides. Just like it says. Its wide at the top and bottom of the case and skinnier in the middle. I cant remember what the cause of this is, but I know Ive read it someone on here before. Any reason why its doing this? I set up the sizing die just like the manual says, put a very minute amount of bell on the case, run the bullet it to 1.14OAL and throw a light crimp. Not sure how to remedy this one.

Round_Gun_Shooter Posted March 6, 2012 Share Posted March 6, 2012 I ran into this using .357 158gr bullets for 9MM. I ended up using a Lee Factory crimp die that has solved the problem. I still have a full box of Berry's DS 158gr that I want to use up. Link to comment Share on other sites More sharing options...

BMartens Posted March 7, 2012 Share Posted March 7, 2012 No remedy required. What you have is the bottle neck look and that is the way it should be. It does a couple of good things for you like no worries about bullet setback and it insures that the round will fit the chamber. Any other dies you use will give you the same effect.

Stuff a bullet in the end and now it has a fat head and butt. Link to comment Share on other sites More sharing options...

jmorris Posted March 7, 2012 Share Posted March 7, 2012 +1 You WANT the coke bottle effect in 9mm! Ahh, the handloaders secret the factorys don't know about. If you don't want to over size the cases use a case gauge to set the dies. It is a taper so the deeper you set the die the more undersize you make the brass.

SERVED_USMC Posted March 7, 2012 Author Share Posted March 7, 2012 Thanks for the help. Made 2 loads up and tried them out really quick. Everything functioned just fine with 3.4 gr titegroup and 1.14OAL. 3.2 was half ass throwing the brass out so I bumped it up a bit. Link to comment Share on other sites More sharing options...
kaiserb Posted March 7, 2012 Share Posted March 7, 2012 My last 20K loads for 9mm have been coke bottled. I like them that way. Link to comment Share on other sites More sharing options...
LPatterson Posted March 7, 2012 Share Posted March 7, 2012 (edited) Not a Coke drinker or snorter but the Coke bottle I saw in the store is narrow in the neck and bottom and fat in the middle. My Lyman Pistol & Revolver manual indicates a .380 neck and .391 at the web, using .355 bullets and allowing for a .011-.012 wall thickness should give a crimp around .377-.379. Hardly a reverse coke bottle shape. RFE dropped a word. Edited March 7, 2012 by LPatterson Link to comment Share on other sites More sharing options...
Jon Merricks Posted March 7, 2012 Share Posted March 7, 2012 What I like about the coke bottle effect is that you can use very little crimp and not have to worry about set back. Link to comment Share on other sites More sharing options...

The majority of the rounds Ive loaded up until this point are 40 so I wasnt to sure about the appearence of the case when I finished the first couple of them. I have a very light crimp and could not get the bullet to set back by pressing it against the bench or chambering the round. I like this. Link to comment Share on other sites More sharing options...

Yep, and the U-die from EGW will make the "coke bottle" look even more pronounced. Link to comment Share on other sites More sharing options...
DsWright Posted March 8, 2012 Share Posted March 8, 2012 my 9 40 and 45 reloads all have the "coke bottle" shape. i never have issues with setback or rechambering. the 9mm is very obvious to the naked eye, the 40 and 45 you really only see if you put the loaded cartridge up against something flat and straight. I use the long end of my calipers and you see a slight cokebottle shape. Link to comment Share on other sites More sharing options...
