Well guys, my smithy finally came clean on his 6.5BPC chambering, it seems he is tightening up the chamber spec's on the Grendel reamer used for gas guns and to save confusion, is calling it the 6.5BPC. Don't know about how much confusion he is saving, cuz I was plenty confused,Just a "Mountain William" from the coal mining area of PA, Cameron County). Hope I didn't have many of you good folks scratching your heads along with me.
