RE: Peep Sight Question
I will bet you that under hunting conditions, the change you are talking about will not only not give you better groups, it might possibly give you worse ones. The target peep is great for what it is named after, targets off sandbags on a bright sunny day. However, when are the best times to hunt: just about light and just about dark. Before you buy a smaller apperture, take the peep you have and try to look through it the last 10 minutes of shooting light. I can't see a thing that time of day through a small peep. Maybe a bullseye, but not a small spot on an animal.
I have Williams twilight peep appeture, which is BIGGER than the stock peep. Works great in the field in any light and I am good out to 150 yards. For me, I couldn't ask for better than that. JMO.
