The biggest difference is the action , barrel length and cartridges chambered for it. the Black Shadow is push feed and the Super Shadow is controlled round push feed. The Black Shadows were not chambered in the WSM calibers and all the Super Shadows are. The barrel lengtho f a 7 mm rem Black shadow would be 26" while the max barrel length on a Super Shadow is 24". The stock on the Super Shadow is much stiffer than the Black Shadow and the recoil pad is better both do not have magazines. The Black Shadow has been discontinued but evidently Walmart and whoever has a pretty good inventory of them. You can buy a Super Shadow for 389 dollars with a Simmons scope ...I just did and they had plenty of Black Shadows for the same price. Now if you buy that same Super shadow outside of Walmart the price mysteriously goes up to about the mid 400's without the scope.. Hope that helps
