I've patterned many a doublegun with "very Full" chokes on my grease plate. I've never seen where, with good quality shot, full chokes hurt patterns. I've got doubles that are choked as much as .048", and they pattern beautifully. Competitors in "card shoots", where they compete to put as many pellets in a turkey target's head and neck as possible, use constrictions as tight as .640". From .729" to .640" is .089" constriction. With extreme amounts of constriction, the smaller the shot size the better, AFA patterns go. Anyway, no full choke vintage doublegun ever made has anywhere near that constriction, and the point is that competitive shooters wouldn't use a choke that ruined their patterns, when they're trying to win.
I love tight chokes for appropriate situations. They make you a much better shooter. One of my favorite dove guns is a 32" barreled 16 ga. LCS with Full and Full chokes. My hit averages with it are just as high as when I try to use a more open choked gun. And, the distances it kills doves dishrag dead deny that there's any pattern problems.
