[QUOTE="Pdvdh, post: 2486916, member: 4191"] You really believe there's not a way to produce an inconsistent bore, or any other machined steel product, in a machine shop or production facility? If it were that easy, no QA/QC inspection would ever be required at most machine shops / plants. I've got a Bartlein with 2 of 5 grooves measuring out of spec deeper than the other 3. Bartlein says it's not possible with their manufacturing equipment. It shoots like a turd. Two of the cut grooves are visible by bore scope across the throat. Chamber reamer couldn't clean them up. Nor did a PTG uni-throater clean up the grooves across the throat, and that tool only centers off the lands. If there's a human, a human manufactured tool, a human programmed machine, or a human operated machine involved, then there's always opportunity for cluster. [/QUOTE]
