Thanks for the reply Will.
I like the cut of those full buckhorns better than the semi-buckhorns but believe I'd have the same problem with them Once the front post fills the rear sight opening, I lose it, especially horizontal. My eyes aren't bad and can shoot lights out with my 1891 Argentine and it has pretty small, fine sights.
Can you get much elevation with that sight? How do you tell how much? Something like 25 yards per turn?
I'm shooting 100 and 200/230 yards, with access to a 300 yard range. Haven't used the '76 on the 300 yet. What are you shooting the '73 at?
I wonder if the distance from a shooter's eye to the rear sight is a lot different between the '73 and '76? Do you happen to know? The '76 has a 28" barrel making the front sight out there a ways too.
The semi-buckhorn was a bit more than an inch closer than the Skinner sight is. They make a ladder sight that brings it back another inch but it's pretty pricey at about 150$. I think the Marbles and Creedmore are less than that.
Thanks again for the reply.
