This is after I lead lapped my .73 cal round ball shooter with peep sights. Light wet wipe between shots.
I replaced the rear 'peep' with a

flat rear.
The front is a post with a Globe.
With this combinatin, sighted dead on at 75yds..........it will shoot under 2"s............it would do better, if I could see better.
Those 550 grain balls hit hard!
