.223 carbide sizing die

Having a problem getting the die to set the shoulder back. Have the die all the way to shell plate plus 1/8 turn. the case comes out about .002 above upper step on case gage. The dies are dillon carbide. Also the expander ball is larger than the one in my lyman die its .222 an the dillon is .223 the when i seat a bullet i can push it on into the case.

RE: .223 carbide sizing die

Not having that issue with my Dillon 223 dies using the Dillon case gage. I was having a problem with the bullet seating die stripping off a little copper ring from the bullet case when pushing the bullet in. Could not figure out what was going on, but did notice that it was difficult to get a bullet started in the case, like the neck was not expanded enough. I pulled my de-capping resizing dies apart and discovered that my de-capper was missing the expander ball. I had purchased the die set from a local authorized Dillon outlet a few months earlier, but had just started using it. I went back to the shop but they would not make it right after such a long period. I have shot off an email to Dillon inquiring about it.

 

FWIW some of my reloads will sit a little higher in the Dillon case gage but well within spec. They do not cause any feed problems with my AR as such.

Update: Dillon is sending me an expander ball free for my missing one on my 223 die. Is this a great company or what?

Agreed Vince, I do love Dillon products and support but I would like the answer to the original question. I am having the same issue. .223 Dillon Carbide Die to the shellplate and getting +.002 on the  headspace. I know it's minute but I'm OCD and it's driving me nuts! What's the answer? I don't have the same problem with the case mouth but the decapper won't pop the primer unless I take the extractor clip out and screw the pin down another .0625 or so

Ok, so the answer is to forget what you know about adjusting dies, throw out the directions and just screw that die down. Way farther down than you would expect. I would never have guessed that putting that much pressure on the shell holder plate was the answer but it is. And oddly enoough, it doesn't seem to hurt the shell plate. I imagine if you don't keep it clean, brass shavings and powder being driven into it by the die would take its toll over time.

RE: .223 carbide sizing die

I am surprised you have to put the die that far down.  My die setting is to touching the shell plate and backed of 1/8 turn. This bumps back the shoulder into spec with the Dillon case gauge and other case gauges.   I recommend a serious cleaning of the case gauge.  And check again.  Testing after resizing and not cleaning the case can lead to incorrect measurements.  Junk (lube attracts dust, etc) builds up in the sizing die giving a false reading.  It is worth a double check and maybe even a call to Dillon.

PS: The concern is not the damage to the shell plate, it would be a concern to to platform where the shell plate rests on top of.  The stress could cause the platform mount bolts to work lossen, causing a need to re-align, etc.
