If you use a drill then yes, you would definitely leave marks that would be an examiner's dream come true. No drill will follow a hole greater than 1/3 its diameter without a lot of chatter. The smart criminal would use a reamer.

How deep is rifling? It can't be much deeper than 0.015 in. I'd start with a straight flute reamer to avoid getting caught in the rifling spiral, then finish and size with a straight reamer and a lot of cutting oil.
+1. Perzactly.
