No but am afraid of a slightly out of round segment banging into the crown during the pulling back of the rod . No such worry with a one piece. I don't know of any top shooters using a segmented rod in a precision rifle
I would think that for the OP "specs" you would want something that will go right through a windshield at 500 yards and still get the job done. Kind of what I want in my SHTF rifle. The Barnes bullet should do the trick.
