I am preparing to hunt cape buff with my Raging Buill in 454. Got a Leupold delta point, great features, the battery will live a very long time, make that seasons! It turns itself off at like 10 minutes with no movement, then will come back on with some movement of the gun, back at the brightness you left it. Lifetime guarantee, and really nice to use. Takes some getting used to, but that's what practice is for! Really makes my groups shrink. One well built piece of equipment. PS----I have 9 years on you!
