The zero had to be set high so I had enough hold over, so I figured 177 yards was a good start. Second shot was center mass on the chicken and I was stoked! Then, after peppering the chicken for a half hour, I moved out to the ram at 236 yards. It was tricky with the changing wind conditions and lobbing slugs that far. Hold over was 21 and 25 MOA with two different slugs, 50 and 55 grains, after the 177 yard zero. By the end of the shooting session the wind calmed and I rattled off a magazine hitting 12 of the 14 slugs. Five of the larger shiny spots are rifle bullet splatters.
