| Hi guys I have 500 rds off loaded 223 left over from my bolt gun witch I no longer have and they wont go in my ar, the bolt wont close on them, is there a safe way to resize them still loaded or is it best to pull them apart dump the powder and resize thanks |

Actually, it is a good idea. Get yourself a Redding Body Die. It sizes the base and shoulder only, leaving the neck alone. You can resize live rounds all you want. Or get a Redding Type-S bushing die and remove the bushing. Does the same thing, but costs more. I'm in agreement with 918. me and my partner actually bought 5k rounds one time of greek .223 it was all outa spec. We just took a die and slightly milled the inside out. With out going into details we made a die that would resize live ammo just fine. The S die will work just fine!

I have 500 rds of loaded 223 ...resize them still loaded I wouldn't do it. Why is this scary? What is the part that is dangerous? A conventional shell holder can't ignite a primer, there's nothing in contact. If the case body is too long, a die that clears the case neck will push the shoulder back the 1 or 2 thousandths of an inch most likely needed. If the case neck or shoulder is buckled, that is a condition that can't be corrected by running the cartridge through a die, so that condition is a non issue to a competent reloader that can diagnose the problem. Same thing applies to a condition with too much crimp on the bullet causing the case to bulge. An attempt to iron the bulge out in a sizer die will fail as the outer diameter of the neck with seated bullet is too large to enter the die. I'm sure it can be jammed into the die, but the force will be high, an indication that it's time to use a different fix. |

While I fully understand being cautious and taking every precaution it seems like that is taken to extremes quite often. |

All I'm trying to get across is that we need to think this stuff through before drawing conclusions that get cause someone to git all askeered.
If a person is still uncertain about their conclusion, it's okay to ask for other opinions, too. But don't post  without including a rationale.

Only real scenario I can come up with is on a progressive machine. On the 550B if you lean the handle forward after sizing as to seat a primer..potential KABOOM Same for the 650 but at station 2. Removing the priming system would be more than prudent. |

Quoted:
Cases lengthen during sizing due to the expander being pulled back, bumping the shoulder and resizing the body should not change the length. When you reduce the diameter of the case, it will lengthen, but only a few thou, but then your die pushes back the shoulder to accomadate the length. wwmkwood: Try removing the expander out of the case and see how much it lengthens if the shoulder isn't bumped back.
