i would do everything possible to stay away from steel shot. i've hunted waterfowl since i was a kid (pass shooting, over decoys on water and in fields). the transition from lead to steel was not good. steel is faster but has no knockdown power. i was always told that steel shot through a modified choke would give you a similar pattern to lead through a full choke. that may be, but you lose a lot in knockdown power. right or wrong, that's my opinion after shooting thousands of rounds of lead andthousands of rounds of steel at waterfowl.
