Got one of the BHW uppers and finally got around to prepping/loading some brass. Have three different brands - SSA, Hornady and RP. Using the Redding S bushing die. The first step with the 285 bushing went well, but when I switched to the 267 bushing the necks were being collapsed into the cases.  Necks were lubed - even tried chamfering the outside of the case mouths. While I have the V-max ammo I purchased with the upper, have not had a chance to shoot it (and reload the brass) - the plan was to load up some heavier bullets to take to the range Monday.  John |

John This is a really dumb question but I have to ask. Did you take the 6.8 button off the shaft? I have seen this before when the fellow failed to do that and just use the decapping pin holder that is much smaller than neck diameter. Greg |

Greg, While I have been known to do some bone-headed stuff (LOL) I DID think to remove the expander!  One thing I noticed about the brass after the past through the 285 bushing - it seemed to have a very slight lip right at the case mouth. May have been due to a bit of springback. But even chamfering the outside of the case mouth didn't help. All I can think of is this being once-fired brass, that and the first necking down reduced the ductility to the point that the neck doesn't want to "flow" when forced up into the 267 bushing. John |

John I think you have found your issue. You might try an intermediate bushing like a 274 and see if that helps. You could try and soften them up with a torch and anneal the necks. That would get you back to square one on the hardness. Greg |

That would get you back to square one on the hardness. Greg I think Greg is right on this one, you will likely have to anneal once fired brass to get it to size down that far. For what its worth, the hornday brass is known to be a bit softer than SSA, while the remmy junk is the hardest. Jace |

I was talking with Ritch and he mentioned that the Wilson bushings made the job go a lot easier as opposed to the Reddings. There is a slight bevel on the Wilsons that make the necking procedure go without a hitch. I happened to have Wilsons and never thought about any differences.

I even tried using a .276 bushing as an intermediate step on new SSA brass but still had no luck. Saw your latest reply and ordered some Wilson bushings. If THAT doesn't work there'll be a 6x68 upper for sale!  John |

Hopefully he's busy working up a load. |

Necks were lubed - even tried chamfering the outside of the case mouths.
