I just want to make sure this is OK I used the Lee universal decapper to decap some privi once fired. Can I take the decapping pin out of the resizing die when I resize. Im 99% sure its yes I just want to make sure before I resize a few hunderd of them.
Thanks |

Quoted:
I would leave it in because the expander on the decaping rod opens the case mouth back up so you can start the bullets easier, unless you have a neck sizer you want to run them through after full length sizing them to get the proper neck size. That is what I was worried about. I did run a few thru with no pin and the neck still opened up. Where I could actually stick the pin into the mouth without it hanging up. Before resizing it was a no go. |

You're not trying to reload cases from American Ammunition (Florida), are you? That crap is the hardest, most unruly brass imaginable and their flash holes are notorious for being off-center.
The headstamp looks like this: A-MERC If you find it, toss it in the scrap brass bin, because that's all it's good for. |

What is supposed to be a convenience feature on the sizer die operation ( decapping pin extension to the neck expander ball stem ), often becomes a PITA as it misses the flash hole, scoots to one side, blocks the stem, and on some of the heavier presses, proceeds to turn the entire expander ball stem into an "S" curve. I have not bought any of the super precision dies ($99 and up) yet. I hope that those have a better control on the concentricity of the neck expander ball stem within the die body. First thing I do with new sizer dies is roll them and see how much eccentricity there is between the expander stem and the die body, usually disappointing. I realize that is a long cantilever from the top of the die body, and the die designers may want the stem relatively loose to avoid side loads on the case during the extraction stroke.
How does the universal decappers work? Do they always hit the hole? |

Note that you said privi brass.
Foreign brass may have smaller flash channels/holes. You could.........reduce the diameter of the de-cap pin. Just chuck it into a drill and w/ sandpaper of a file "get busy." Or......drill out the brass......... DE-CAP PINS/FLASH HOLES
I measured my old style “straight” RCBS pins. Anywhere from 0.841" to 0.926" in length Small diameter....... 0.60" Large diameter....... 0.70" In an emergency........drill rod or similar would work. ++++ Q. What is the proper diameter for flash holes? A. Military specifications for flash holes are .078" + .004" for 7.62 mm and .30 M2, and .080" + .004" for the 5.56 mm. Commercial cases of all calibers use similar dimensions. You can use a 5/64" (.0781") and a #45 drill (.082") as min/max gauges and be well within tolerances. Most folks simply standardize on a #46 (.081"). Note that some new commercial "lead free" ammunition uses a substantially larger flash hole and according to several sources these case can be reloaded normally. taken from: http://www.frfrogspad.com/miscellj.htm#flash _________________________ Or.........next time only use brass "Made in the USA." OK........FREE......foreign, good quality brass, might be a major exception.
