I shot some Fed. HW 7s through one last year. They shot OK but didn't impress me like my Carlson's .575 did. What I did notice was that it really took some chunks off the wad, leaving pieces of it laying on the shooting bench with a few pieces even hitting my arm believe it or not. My jelly head for my 835 on the other hand shoots them really well...who'd have thunk it?...
