RE: 12 ga. chokes
Also remember that larger shot sizes, harder shot (like copper plated, or the new tungsten and heavy shot, and steel), and higher velocity loads will pattern tighter in the same choke than smaller, softer, slower loads.
For instance, I use full choke when shooting trap (any range) because I use #8 target loads. This helps give me tight patterns, good breaks and also lets me reach out farther. When shooting skeet I prefer imp. cyl. (an actual skeet tube would probably be better, but I don't have one) because of the relatively short ranges and speeds of the birds.
When hunting pheasents I like to use modified with #4 high velocity heavy game loads. Good range without turning the birds into red mist and a memory.
For "rifled" slugs use imp. cyl. for best accuracy.
