    The bolt nose on a rem. 700 measures around .690 and the barrel counterbore is usually .705. Don't know how much pressure this translates to but I'm guessing it's a lot.

    After rough drilling I set up the taper attachment on one of my heavy 10's and bore my chambers leaving about .005 on a side. The front of the reamer does most of the cutting although I guess that's...

    Butch,
