Just a note for any of the guys that are concerned about drilling tips to help ensure expansion. You pobably really only need to drill your hunting rounds. From the limited testing I've done, my impacts/grouping didn't change. So I dont personally feel the need to drill every bullet I fire, only the handful I plan on taking hunting. For that matter, you could possibly just get away with ensuring there are no obstructions with a pin... but I havent tested that one. YMMV.
