The Hornady primer pocket reamer is about $10 per bit or a little under $20 for both. Choose the one you need and chuck it up in an electric drill then go to town.

At first I used the "old timer" method of a pocket knife (box cutter) but quickly learned that the old timers were either crazy, stuck with an inferior method because they didn't have better tools, or both. 100 cases or less convinced me to pony up the 20 bucks.
