Every unsuccessful hunter knows that missed game is the gun’s fault. Sometimes a skilled hunter can “rehabilitate” these faulty guns.
You might try sending the gun to a successful hunter to see if they can rehabilitate it.
However, these guns are know to “reaquire” their bad habits at inappropriate times.
You might be right but... full disclosure, I bought it from a successful hunter. Sigh... I’m afraid the problem is with the stock: it’s tucked into the wrong shoulder. Actually there might be something to that. I’m at least average with my other shotgun (Mossberg tactical style) and average to somewhat better than average with my rifles. Maybe we’re just not meant for each other? It’s not you, it’s me...
