Here are Johns pictures.
John I spoke to George U. yesterday and he said it sounds like a deformed core issue of possible the punches.
Have you spoke to Blackmon yet? Outside of the marks they look good. Michael

Are you talking about the punch that ejects the bullet from the die after forming? If so, this diameter is .0627". Why do you ask? John |

I had a sample sent recently with marks like that.
I believe they're caused by a scored die bore from running dirty jackets into the die. I've caused it on sizing dies, even once on carbide. dirty case I saw just as it went in and wasn't quick enough to stop the stroke til too late. A good polishing should take it out. Have doubts if the makers of these will back it up like Lee or rcbs will their dies. Sure pays to be careful of what you put in them. Can happen so quick it's hard to believe.

John, I'm refering to the diameter of the external punch...the one that pushes against the base of the jacket and pushes the cored jacket into the point up die. -Al

I'll get the names for each of the pieces figured out soon. The diameter of the external punch is right on .243". Why do you ask? John |

John:
Have you checked the edge of the bottom punch? IS it rough and maybe overly large, or out of alignment with the bullet you're pushing in the die? Where the pin might be running against the bore to scratch it? It's possible he let it slip out the door without final polishing of the bore. I still think that can be polished out. But, it's going to take several minutes and tries. IF it came that way and sounds like it did. You should be able to swap it to the maker for a good one, or else he should fix it up. Good luck, let us know how it turns out and what he has to say.

George knows what I'm getting at.
If the leading edge of the punch has a raised 'lip', it can cause a mark. I've dinged a punch on my .30 setup..so I've been where you are. Just something to check...make sure the leading edge isn't 'belled' or has a lip on it. Hope this helps. -Al Last edited by Al Nyhus; 02-22-2008 at 09:49 PM. |
