Baited bear hunt coming up. Am anticipating a shot at around 60 - 120 yards, likely towards dusk.

Is the 2.5x Leupold I've got in QD rings on my 45-70 Marlin going to be bright enough?

Or should I swap on something else? I like the little 2.5x Leupold on that rifle, but... Wondering if it's enough for this hunt. I've got a good ol' 6x Leupold with the 36mm objective and also another with the 42mm objective that I could just use instead. Thoughts?
