Well, this was on my shooting bench yesterday!
My Model 71 (348 Winchester) got a Skinner Sight's bolt peep with an .070 aperture and shot a 1 7/8" 3 shot group at 100 yds with my handloads.
I took my first 3 deer with this gun, but then retired it when my eyes and open sight were no longer compatible. I would not install a Williams peep as it would cover some of my engraving. The Skinner Bolt Peep resolves that issue.
This gun was manufactured in 1940, I purchased it when I was in college in the early 1970s, the owner had passed and it was on consignment. It has always been my favorite gun, and is a real hammer! Looking forward to hunting with it again this year. (That is a Hornady Leverevolution 200 grain bullet, which they stopped selling to reloaders, they still sell the loaded ammo). Luckily, I have a supply, and hopefully they will start selling it again in the future.
