Lloyd3,
Lloyd, my comments are based on my experience and advice from bird hunters (quail hunters) when I was growing up. I have opened many many old side by sides and closed a few via jug choking. My experience relates to 20 and 28 gauge guns and a few 16 gauges. Based on my experience the smaller the gauge the more important the choking for good hunting results.
I was taught to pattern your gun with the brand of shell and size shot at the distances you plan to shoot because different guns with the supposedly same constriction may pattern differ brand shells or shot size differently.
I like playing the game and believe each gun, especially older ones, have to be adjusted according to observed results.
Take Care,
