I put an Omega peep blade on a 10 1/2" SBH in 1978 or 1979 and shot a few wildcat silhouette matches with it. I was surprised at how well it worked, but I felt it was delicate, sticking up as far as it did, and removed it. I never hunted with it.
In the early days of metallic silhouette shooting, many receiver peep sights were put on Unlimited guns - XP's, Super 14's etc, but they faded away rather quickly due to the match winning superiority of square notch rear sights.
