RE: Peep Sight Question
If you were hunting from a blind on a nice bright sunny day, then the target peep would be a good thing. If you hunt like me in shadows, marshes, and normally only see game at just about closing, there are times your better off with the apertures removed and shooting just the ghost ring.
I have a Williams Peep on a Traditions Pioneer side lock. No idea of the size, but it is a nice sight. Very accurate also.
