I killed my 3rd bird at 7:42am this morning with the Hevi #7 and I'm sold on them after killing 7 birds in 2 seasons with them, get'em at 40 and in and they are lethal to 40 and a fudge factor of a couple yards further, I've shot them this year from 20 to 42 yards and all were doa with just a little flopping.
