Have you checked the barrel channel, stock, bedding blocks, etc.? If you're sure it ain't the scope, check the stock. If it's not the stock, start checking the headspace, chamber, and receiver/barrel interface, etc. Also, if you could post up details of what it's actually doing it might help with some ideas....vertical/horizontal stringing, wandering zero, third shot flier, what direction it seems to throw a shot, etc. :mrgreen: Nothing ever shoots in the same place twice, but are they all to 3 o'clock, random in a 6" pattern, etc.?
Here's a thought: Let the ducks work and decoy.
