I was practicing some trap yesterday in lieu of a pheasant hunt and found an unusual occurrence Shooting a Beretta 682 Golden E, 12 gauge O/U and switching barrels, too, I had to pull through the target to break it with an Improved choke at 16 yards as oppose to shooting Modified. With Mod, I just held underneath and smoked 'em every time. I was shooting at them "out of the house". May be 20 yards at most. Can anyone explain what was going on?
