You already have the perfect setup, you don’t need the best glass on the market, you’re going bear hunting not competition bench rest shooting. I just got back from my 6th successful brown bear hunt in Alaska in May and on all of those hunts I used a 2x7 or 2.5 x8 Leupold except one time I used a 4x12 Leupold and I didn’t care for it on that hunt. I just don’t like that scope, period.
My last hunt was with a 2.5x8 Leupold on 338 Edge plus P. The whole setup weighs under 8 pounds and one of the guides did his best to get me to trade him even up for his Weatherby 338/378 with a big ass Leupold on it. He wanted it because it is so lightweight and practical.
