Nice pics Frank,

Looks like a zoo over there! The animals over there obviously don't fear humans. What's that first animal in the petting zoo? No St. Pauli Girl though

Although your groupings are not too bad for getting started (but I don't know the distance), looking at all the different entry angles on those arrows, I do not think your bow is well tuned. Unless it was real windy or after hitting the target it moved for your next shot, the shafts should all be fairly parallel to one another (and not have random angles). I'm thinking with all that playing with the sight, that it is not properly aligned. The arrow can make its way back to center, but it will have erratic flight and decrease your accuracy. What is your range on these shots and is the target moving?
