vwynn Posted May 23, 2011 Share Posted May 23, 2011 Hey all been experimenting with the rcbs small base 223 die set.. i tried to resize/deprime some of my brass and found they are making wierd neck shapes. Please see pics. any suggestions? i found that backing the deprimer stops the double bump thing but the neck is not sharp anymore :/ Link to comment Share on other sites More sharing options...

DinosaurMikeGolf Posted May 23, 2011 Share Posted May 23, 2011 Have you checked the die for possible obstructing material? Link to comment Share on other sites More sharing options...
Younger Posted May 23, 2011 Share Posted May 23, 2011 Take the die apart and clean it. What type of lube are you using? Link to comment Share on other sites More sharing options...
Kevin G. Posted May 23, 2011 Share Posted May 23, 2011 Are you using an RCBS small base X-die? The X-die has a mandrel on the expander/depriming stem that is supposed to stop the cases from growing in length once they are trimmed and the die is set. There is a procedure you must follow to get that die to work correctly. Since your brass isn't trimmed to a uniform length, the longer cases could be deformed (like the double bump) if the stem is screwed into the die. As far as the transition from shoulder to neck .... I would verify first that the die body is screwed far enough in. Link to comment Share on other sites More sharing options...

Younger - I took the die apart and tossed em in the tumbler to clean intially. Afterwards sprayed it with brake cleaner to clean watever was still there. DinosaurMikeGolf- dont think theres any obstructions but ill check when i get home Link to comment Share on other sites More sharing options...
Aaron M Posted May 25, 2011 Share Posted May 25, 2011 How far are you screwing your die into your press? what type of die is it? does it use and expander ball of a bushing and a plug? it looks to me as if the neck is not getting sized all the way down to the shoulder, but your shoulders also looked messed up. Stupid question but are you sure this is a 223 die. Link to comment Share on other sites More sharing options...
bgary Posted May 25, 2011 Share Posted May 25, 2011 Stupid question but are you sure this is a 223 die. You might be onto something - the neck looks "too big". Could be the wrong die (with correspondingly wrong expander ball)? Link to comment Share on other sites More sharing options...
Chills1994 Posted May 25, 2011 Share Posted May 25, 2011 my first gut reaction when I saw those pics like last week was correct sizing die wrong expander ball or mandrel. RCBS has really good customer service and I think a lifetime warranty. so if you can't get it to work properly, package it up and send it RCBS. they'll probably just send you a brand new one for free. you should try calling RCBS first to confirm their address and the procedure for sending it to them.

vwynn Posted May 25, 2011 Author Share Posted May 25, 2011 (edited) heres the die set. I added the LNL bushings to it since this is for my Hornady LNL AP. im perdy sure its for a 223 since it fits nicely. Edited May 25, 2011 by vwynn Link to comment Share on other sites More sharing options...
vwynn Posted May 25, 2011 Author Share Posted May 25, 2011 ok yes 100% sure its 223 hah. hmm i will be tinkering around with the dies again when i have time... after midterms and finals. my dies are screwed in all the way till they touch the shellplate. i think the culprit MIGHT be just me being a noob and not adjusting the die properly... but who knows Link to comment Share on other sites More sharing options...
Graham Smith Posted May 25, 2011 Share Posted May 25, 2011 FWIW, I started out using the small base die and had so many problems with cases sticking unless I slathered the cases in motor oil (that's sarcasm) that I sold it. Later, I was told that you probably only need to use this die if you are trying to resize brass for a .223 (not 5.56) semi-auto with a tight chamber.

vwynn Posted May 27, 2011 Author Share Posted May 27, 2011 here are some updated pics of some more resized brass... how do they look now?? Link to comment Share on other sites More sharing options...
DyNo! Posted May 27, 2011 Share Posted May 27, 2011 how do they look now?? Got a case gauge that does headspacing? A hell of a lot more effective than eyeballing them! Link to comment Share on other sites More sharing options...
vwynn Posted May 27, 2011 Author Share Posted May 27, 2011 haha.. ill be needing to add that to the buy list. man loading necked brass is a PITA ... Link to comment Share on other sites More sharing options...
DinosaurMikeGolf Posted May 27, 2011 Share Posted May 27, 2011 Get the EGW (Evloution Gun Works) Case Gauge in 5.56mm if you load both .223 and 5.56mm. Link to comment Share on other sites More sharing options...
kamikaze1a Posted May 28, 2011 Share Posted May 28, 2011 You know, it might be an illusion but the length of your brass seem to be all over the place. Is the surface you have them standing on flat? Even some of the shoulders do not seem to align with the shell next to it... Link to comment Share on other sites More sharing options...
vwynn Posted May 28, 2011 Author Share Posted May 28, 2011 ill look into the EGW. my brass are mixed 223 and 5.56. and my gun is 5.56 chamber so whichever works. Kamikaze1a - Yea the lengths are all different since i have not trilled the cases yet. My plans were to size it and then trim it to spec so that everything is consistent in the end. Hopefully that method aint bad? Link to comment Share on other sites More sharing options...

Hopefully that method aint bad? The IGW gauge is cut using the actual chamber reamers so any case that fits in the gauge will fit your rifle chamber.
