It's close enough that you won't notice a difference...except in the price. Even thought Alliant advertises it as a direct replacement for Clays, be sure to verify the Clay Dot drop weights with a good scale.
I had to change to Clay Dot from Clays and I found it's just about the same. However, I use a little less. It has a little more kick and is a touch dirty as compared to Clays. A lot cheaper during normal times.
