Looks like gpc brass will work with out fire forming. Just neck up and bump the shoulder where needed.  |

Isn't the GPC a 27 case in it's original design so would need to be necked down not up?

I had been talking to a bunch of guys on the 6X6.8 over the last few days. Yeah you will be fine but trimming will be needed with what ever you use. I wouldn't bother using the GPC at all if it were I. Generic 6.8 would be a bit more available and cheaper. The shoulder massage on the 6.8 will be fine with standard stuff and you won't see any true accuracy difference at all. Greg |

Problem with my chamber is fire forming I've found depending on the 6.8 brass the shoulder is back far enough it dont fire just necking it up so I have to load long or do the cornmeal method |

You must have one of the tall shoulder later production chambers. The GPC would be ideal for that problematic issue. One could also use HAGAR brass but that's a long row to hoe to get there.
