I keep looking at this fine shooter and I think there is only one thing I would change and that is the rear sight. I would replace that buckhorn with a Lawrence, for two reasons for hunting that tall ear buckhorn will dig in the hand because it's right at the balance point where you carry it.
And second you have several preset set of elevations for quick shots. But again with the buck horn you also have that option but you would have to take time to learn how the use the ranging features of the full buckhorn. It has 4 one can use with some practice.
I wish my .50 looked like yours.
It has a nice straight grain I the wrist where you need the strength for a thumper like the big .50.
