RTSJ, Sights would be a great idea for back up and versatility, but don't just have them put on, shoot with them, alot. Based on two sets of torqued-to-spec talley lightweights that I had crack on a .308 and a .300 WSM, I'd never trust them on any flavor of .416, even with a light scope like the Leupold 2.5. The Talley QDs are another critter entirely. The ones on my '06s, 9.3s, .375, .416 and so on have been stellar over the course of many, many rounds.
