Deeper in the article they mention 3 yards and some out to 5 yards.. I've never conducted this kind of test but by shooting all buck shot sizes at standard Bianchi Plates ( 8") out to 30 yds # 1 buck was the only one that would knock down the plates at that range, #4 was a waste of time as was 00... I also have tried lately the Controlled flight buckshot (00) and it is the best for reaching out a ways.. I do wish they would make that load in #1 buck...how far away were they from the gelatin when they fired? I didn't see that, only that they were taken from a "known distance"
i'm guessing it isn't muzzle to gel close but are we talking about 3 feet, 1 foot? are these representative of a target that would be in ones home at a distance of say 10 feet?
