They are all dead birds I am thinking. I haven't tried too many of the Fed 7's. Seems like they are hard to find when I am in the mood and looking. Have you tried the hevi shot 7's? My 20 likes them real well.
Yes, there is a Hevi 13 7 pattern in those pictures. I believe it was the 2nd picture. They shoot good out of my remington 20 ga 870....they average 155 out of a truglo SSX in that gun, but the same choke also throws a 145 pattern with the federal 7s. I prefer the federals over hevi since they are so much heavier.
What Im impressed with is the Fed 6 pattern out of the purgold. This pure gold shoots a 90 to 100 type pattern with the 7s. It looks pretty good with the 6s.
