I'm lurking as usual. And it looks like you are right 9three. Don't know nothing, means they know something. Double negative is still positive??? I enjoyed this data from different researchers and shooters. I had the feeling from my limited shooting that the Ghost ring and a flat topped front is my personal favorite. My squirrel gun, an old Golden 39A has a receiver peep and a front bead filed to shape. Flat. That is the gun from which I shoot the most ammo each year. My favorite big bore, a Savage .458 Win Mag had an Ashley peep and Brockman's flat top front post with brass inlay. Wish I hadn't sold it. Good shootin' boys and girls. And God Bless. Rustyzipper
