I'm so bad with a shotgun that I don't take shots outside 30yds. At that range #4 SHOT would probably work, but I would never do that because...why would I with so many other good choices out there, but I'm off topic now. My point is this, I have patterned my shotgun out to 45 yards and it will throw an absolutely evil pattern out to that range with my load/loads and choke combination. But the limiting factor in my equation isn't my hardware, it's lack of talent, hence the 30 yard limit.
