Most likely what you are encountering is the beveled edge of the meta peep. G5 bevels the inside edge so that if the peep isn't perfectly square, you can still see through it. You know what I'm talking about......it's those times when the string twists just ever so slightly. W/ that beveled edge, you can still see through it.
I know about the beveled edge but don't understand if that is the problem then why? I have a tube style aligner on there so my peep is always square.
You know, it's probably the case that poorer lighting just blurs any sized peep altogether. What I mean by this is that if I'm shooting outdoors, I can see the entire outline of my peep very clearly. -meaningoutside diameter and inside diameter edges.When I'm indoors, it blurs and the walls thickness of the peep seems to thin out so it's sloppier and harder tocenter with the pinguard.
Anyone else notice that indoor groups are not as good as outdoor groups regardless of what size or what brand of peep you're using?
