I just started reloading .300 blackout & all my brass went through the resizing without a problem except all the Fiocchi brass. I bought 100 rounds of Fiocchi just to have brass to reload but after shooting through my gun they won't go through the resizing die.
It will only go into the full length resizing die to line I have marked in this picture. 
I have tried all kinds of lube, all of my other brass fits through the sizing die easily. 
If I try to force it through the press it locks in the die & rips the extractor ring off, then I have to take the die apart to remove the stuck brass. I learned to cut the .223 brass & resize it but I would like to find a way to use my Fiocchi brass. I'm not sure if the Fiocchi brass is too hard to resize,(the only reason I can think of) it is the same thickness as the other brass that I processed. Has anyone encountered this problem in your reloading? |

Someone else mentioned problems with GFL 300 blk brass. I just remember they had problems. Would be the last couple of pages of this thread IIRC. |
| I have had GFL 223 brass jam up on a decapping pin because of a tight flash hole. Can you remove the decapping pin and see if you have the same difficulty sizing? Also, take a picture down inside the case and see whether it has one flash hole (boxer) or two (berdan). |

Quoted:
Are they boxer primed? Sounds like they are berdan primed and the depriming rod is keeping your die from resizing further. Quoted:

I have a couple hundred pieces of GFL brass that sized with no issues. What brand die are you using? Quoted:

Also, take a picture down inside the case and see whether it has one flash hole (boxer) or two (berdan). I know the difference between boxer & Berdan. These are boxer because I have tried using a small pin to knock out the primer then size & it still gets stuck. My (Lee) full length .223 sizing die runs the GFL .223 easy, just got through sizing over 2k of them. 
How hot do I need to get the cases to anneal them, will a propane torch do it? |

What .300blk dies are you using? Are they small base dies? What kinds and how much lubricant are you using on the cases? Are you tumbling or cleaning the cases before running them into the die? Can you measure the diameter of the Fiocchi brass below the line where it stops in the die, compared to unsized brass that sizes properly in the die? Also a comparison of the case diameter above the Fiocchi line and on a fully sized case? What decapping die have you tried that gets stuck? Also what is the diameter of the decapping pin it uses, compared to that of your full length sizing die's? Can you see inside the case to inspect the flash holes for any kind of deformity, burs or to see if they are off center by some amount? To answer one of your questions: yes a propane torch can anneal your case necks. The target temp is 750 degrees F, use an indicating liquid like Tempilaq to make sure you do not exceed this temperature and ruin your brass. |

Quoted: Dryflash did a great thread recently for "Low Budget Annealing". Method works well for me. Uses a propane torch and 750* tempilaq. Worth finding the thread. Currently on page 15 of this forum. You Must use 750 degree Tempilaq or you are wasting your time and overheating your cases. Tells all about it in the thread. Good luck |
