As noted, Hodgdon has the Featherlight formula on its website. Unless the target is malfunctioning a featherlite will take down any KD if you HIT it. In the good old days most shotgun targets were fixed or spring loaded and there were always arguments about "goldern BB's.) Most clubs and every major match have gone to KDs since there is no question about golden BB's. The target is up or down. One thing to be careful of with smokeless powder, including shotgun loads, is not to go wild trying to get the lightest load possible. Smokeless requires a certain amount of pressure to work properly and to burn efficiently. I have seen a couple of shooters at some local matches that are down loading their shotguns so low they are getting really inconsistent loads. These guys were wondering why they had a ball of flame in front of the muzzle, but still couldn't knock down the targets. The answer was that the primer was blowing everything down the barrel and the powder was igniting when it hit the atmosphere. If you read the manuals they tell not to change anything, the wad, hull, or wad when following a recipe. Smokeless powder ain't peanut butter and jelly and it's not just a matter of adding more or less.
