| Do lee dies have a larger primmer removal pin? I cant remove the primmer out of a couple pmc brass cases it just pushes the pin out of the die its not berdan primmed has anybody else ran into this? It worked fine on the LC brass |

The cases you have may have a smaller than normal flashhole.
I use a Lee universal decapper die (with the collet real tight) to decapp and swage the flashhole larger. Lube the decapping pin, then every 4 or so cases. Otherwise the decapping pin will pull out. BTDT. |

Strait from LEE's FAQ pages
Quote: Decapping die adjustment The trick to adjusting the decapper is to just tighten the decapper clamp enough so that the decapper will push out 90% of the primers, but the very stubborn ones will cause the decapper to slide up through the clamp. Start with the decapper clamp just tight enough to keep the decapper from falling out the bottom of the die. Try to resize a case. The decapper will probably slide up through the decapper clamp. Tap the decapper back down flush with the top of the decapping clamp, tighten the clamp another 1/8 turn, and try again. Repeat until you successfully deprime the case. |

It worked fine on the LC brass First........PMC is foreign. So, I don't expect all foreign brass to be made to the same "standards" as American brass. And, I can't say about LEE (never measured mine) but these measurements may help........... 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 Aloha, Mark |

okay i sat down and played with the brass a little more today, still cant get it deprimmed, Its the latest brass i have shot, its got a red sealant aroung the primmer... Its more like super glue. but anyways either its one hell of a crimp or the red stuff holding it in. I can make the primmer bulge outwards but not move the primmer. So im just gonna toss those its not worth a bent or broke deprimming rod.
Also anybody have pictures of dents in cases that may be okay to reload and some that are no good. My gun dents about 90% of the cases ejected but some are deeper than others. |

I use the exact same die and exact same press as you....I love PMC brass...The primer pocket crimp is more apparent than most.
Just crank your the nut on the top of the die as tight as you can get it. At least that's what I do and I haven't broken a pin yet. YMMV |
I recently did 1500 pieces of PMC with the sealant you describe and didn't have a single problem. Using Dillon dies. Your right in that it's not worth breaking primer pins but I'm really surprised. Maybe try soaking the brass in acetone for a little while to desolve the sealant and retry. You could have always gotten some brass that they did a very good job of crimping.

You could try (my step #2).......
2) With once fired military brass, this next step only has to be done once. You could de-cap primers with the standard de-cap/re-sizer die. Though due to the primer crimp, there is a high incidence of parts breakage. IMHO, de-cap the once fired military brass using either, a “universal” de-capper die or with a skinny nail/punch and anvil (with a hole in it, large enough for the old primer to fall out of, but still support the case rim). Or, buy the LEE military primer de-capper set (#90102-.30 cal., #90103-.22 cal.). Simply, run the nail/punch down through the case neck. The nail will enter the flash hole and rest against the old primer. Put the case on the anvil (old primer centered over the anvil’s hole). Then, with a hammer knock out the old primer, letting the old primer fall through the hole in the anvil. Yes, the military crimp is sometimes that stubborn. HTH. Aloha, Mark |

Used to have the same problem with some really old foreign military 9MM brass. Even to the point (if I really wrestled with it) of the decapping pin actually poking a hole in the primer itself.
In that case it was clearly caused by a super heavy crimp. I finally just threw all that brass away. Nowadays if I get a really stubborn primer, I switch over to a manual decapping rod as described by ma96782 above. However, I simply use a replacement Lee decapping rod such as this: http://www.midwayusa.com/viewproduct/?productnumber=274540 (Though with this you will need something to set the case on as the primer is knocked out.) |
| I have on occasion broken out the HAND Lee decapper tool. It's a punch and an anvil; you place the head of the cartridge in the anvil, slide the punch in through the mouth until it slides into the flash hole, and then WAIL on it with a mallet or hammer. I've yet to find a Boxer primer that I couldn't "encourage to leave" with that tool. |

PMC brass has been known to have off-centered flash holes. Could this be some of your problem? This... I've seen this with some of my brass... I still get it deprimed, I just use a smoother motion, and the pin and spindle (I use Hornady dies) flex a bit to knock the primer out. It's rare (in my case anyway), but it is with PMC brass almost exclusively. |

I recycle these off center flashole cases, because I don't want problems. But if his decapping pin is hitting brass, he's gonna have a problem. I have seen some way off flash holes in PMC brass. |
