Some people think you have to relearn how to shoot steel because it has a different "feel," starting out fast and slowing quickly. I think the "feel" you need is a feeling of confidence in your ammunition. A round of sporting clays with my dove gun and loads before the season convinced me that if I point my gun at targets the same way I do with lead, they break solidly.
In the Field**
While lead beats steel on paper, I can't complain about steel's performance in the dove field, and neither can my friends who stocked up on steel dove loads before the non-toxic restriction was lifted. I have hit more than I missed and killed a few at longish range. I have seen only one bird hit hard that kept flying, and that one I marked and found dead where it landed. There is even one added benefit to steel: when I do miss, I get to blame my ammunition instead of myself.
