I picked up a flat of Spred-R 1 1/8 ounce #7 1/2 shot 12-gauge 2 3/4 inch loads at the going out of business sale at the old Potomac River Gun Club. I used some of them in my Father's old tightly choked 2 frame Parker Bros. waterfowl gun. I shot a couple of patterns with each barrel and in that particular gun the results were very patchy. Just my experience with a very limited test. Maybe in a different barrel they would give better results.
