Hey man,
I had the EXACT same problem a couple of weekends ago, but in the last 3 minutes of shooting light, I couldn't see my pin through my peep, but I could still see the deer! Because of this, I too am buying a new sight! Since I am also a poor college kid, I will let you in on my secret , Here is a sight off of ebay, this guy has 100% feedback, and I am fixing to buy the exact sight in 2 days. This one ends in 4, and if you don't get it, He will put more up as they go off. Just don't bid against me!!! Good luck!
