Does anyone know how steel shot compares to lead and similar substitutes in respect of trajectory ie when the shot starts to fall off compared to others, effective range, and energy. I shot some ducks eith steel the other day that were within 40yds and some of the pellets ended up between skin and muscle. The pellets should have penetrated to the vitals. Futhermore I could swear that although I was leading the birds as I would lead targets that I shoot lead at, the shot string was behind. This was in the range of +35 yds.
