I use a Skinner peep sight with several different sizes of apertures on my Henry 45 Colt and really enjoy the challenge of it. At 56, it's not as easy as it used to be but I'm still amazed at my groups.

I also shoot my father's old Winchester Model 75 22LR target rifle that is equipped with an adjustable Redfield peep sight. On a good day, it can rival my scoped 22LR rifles at 50 yds.
