Ream with plenty of WD40. It should come out pretty nice if the reamer is new, sharp and well aligned with the hole.
If I was being fussy, I would drill it, then bore it, leaving .005" to ream. Take care with the reamer, to clear the chips before you go for the bottom of the hole, if it is a closed ended cylinder.
I might also attempt to polish it a wee bit with crocus cloth (rouge). Use maybe a 1/4" dowel, hacksaw a lengthwise slit down the end for about an inch. You then insert one end of a strip of the cloth through the slit, and then wrap it a couple of times around the dowel, with the abrasive side out. Keep it wrapped with fingertip pressure, until you get it into the hole. Then, you can polish as you see fit.
