RST has not stocked Nice Shot in years
you can still get Nice Shot in bulk for reloading - sizes 6 and 7.5 great stuff- just pay attention to the pressure- they say it adds 1500PSI - but with one load i had tested it was 2000 over the data in the Lymann book

i have had good luck with it on duck in the larger sizes
Kent TM is great stuff - a little pricey
