Strange baryons have long been known to exhibit a leading particle effect. A recent comparison of $Xi^-$ production in $pi^-$, $n$, and $Sigma^-$ interactions with nuclei show this effect clearly. These data are supplemented by earlier measurements of $Xi^-$ and $Omega$ production by a $Xi^-$ beam. We calculate the $Xi^-$ and $Omega$ $x_F$ distributions and nuclear dependence in $hA$ interactions using the intrinsic model.
