I put that choke in my son's tri star and shot both no7 heavy13 and Federal heavyweight #7.I don't count the number of shot in a 10" circle.I put a turkey target up and look at the results.Up to 45 yards,it's deadly.I actually think the heavy 13 patterns a little better but both are great.He killed two gobblers with the heavy 13,one at 35 yards and one at 45 yards.Both were dead right there.Last week he killed another one with the fed #7 at 36 yards and it flat out smashed the bird.
I bought the same choke this past year for my Franchi Affinity in 20
ga.It shot the federal great so I just stopped there.This morning I killed a bird at roughly 35 yards and the peformance was text book.
