I have a 10 month old M2 that is great in every way except one. It shoots 6 inches high at 21 yards. I have tried going to the "C" shim and it changed nothing. Benelli says that is within their specs. I have 5 other shotguns that all shoot point of aim at 21 yards. I don't understand it, but unless you want to try re-learning your shooting technique, I'd recommend another brand of shotgun. I don't know if a gunsmith can help me, but this does not seem "World Class" to me. The first customer service "lady" I spoke to said maybe my barrell was bent.
