I'm using a RCBS press mounted swager. I have had no issues from it until today. I switched to Dillon .223 dies. When I started swaging the brass I had used the dillon sizing die on, they will barely go over the swaging rod, if at all. It is happening across different headstamps, not just one type of brass.
Has anyone else had this issue? |

Why are you sizing the brass before swaging? Personally I think swaging, sizing, trimming is the correct order of operation. Try a case that has not been sized yet. Because it sizes and decaps at the same time. Brass can't be swaged unless the primer is out. I did not have this problem sizing and decapping with RCBS full length and small base dies or Lee dies. |

I believe you'll find that all Dillon dies are equivalent to small base dies. A friend of mine uses a small base die to tighten up the primer pockets slightly once they begin to enlarge to get a few more firings. Might explain what you're experiencing. My problem has to do with the case neck. The RCBS press mounted swager has a rod that goes down through the case. The rod doesn't fit through the neck with the dillon sized brass. I just grabbed 10 random, unsized pieces of brass. All 10 slid over the rod with no problems. Looks like I won't be able to size and decap with Dillon dies and swage with the RCBS press mounted swager. Very aggravating. |

Has anyone else had this issue? I don't think the sizing die has a bearing on this. I have Dillon, Hornady, and RCBS 223 sizing dies. With different headstamps the web thickness varies. Which means you should sort cases to headstamp, adjust rod for that headstamp, then move on to the next headstamp. As long as the primer pocket starts over the swaging spud the swage will be fine. You are right to size/deprime before swaging. Be careful to not over swage. Swage a case and seat a primer. If it doesn't seat, adjust for more crimp and try again. If primer seats too easy, well you only ruined 1 case. Adjust some swage out by raising rod. If you can post a pic of what you think is the problem.

I just tried 10 unsized, random pieces. No problems. |

They must of made the rod diameter much larger when they "improved" this tool because the rods bent a lot. Due to improper adjustment. If you have a decapping die, decapp first then swage. |

Quoted: 1) Make sure you are using the correct rod. 2) Make sure that the end of the rod has not gotten larger in diameter from being compressed (mushroomed). Motor Think you guys hit it, OP using the 30 cal rod on 223 cases. It's been 15 years since I used my RCBS swager. |

The OP said the rod fits a fired case but not a sized case
To me it sounds like he's using the correct rod Fired cases necks are larger than sized cases I know you know this, when you size a fired case, the neck diameter is reduced, usually more than needed Then the sizing button is pulled through the neck to open it back up to accept a new bullet. The size of that button effects how much the neck is opened up. There are other methods of doing this, like bushing dies and mandrels. |

Motor Think you guys hit it, OP using the 30 cal rod on 223 cases. It's been 15 years since I used my RCBS swager. Maybe. But I'm leaning towards #2 because he said it will fit through a fired case. It probably wouldn't take too much mushrooming to make it not fit although the set I have has been used and abused but still works. I'll go measure the parts and edit this post. The small rod in my kit is .220" diameter. The OP either has an oversized rod or a mushroomed one. The large rod is .260" so that rules that out. Motor |

Dillon expander measured .2105. RCBS expander measured .221. The rod on swager measured .217. Holy Cow!!!! .2105 ? I think you found your problem. Does it even contact the inside diameter of the neck? I don't have Dillon equipment so I can't say if that is normal but I wouldn't think it should be that small. I'm sure you will get good answers. Lots of Dillon users here. Motor |
