RE: Peep sight?
I grew up shooting and hunting with peep sights and I still like them, we could never afford a scope. I try and use a Williams 5D (it used to cost $5). I've got them on my Marlin guide gun, Win 30/30, Thompson Center Black Diamond muzzle loader and I carry one in my pocket from Sako that fits on the scope dovetails should a scope fail in the field. For me, they're much faster than scope in heavy cover. I find myself hunting around for the target in the scope, with the peep it's always right there.
