The CleanShot loose powder is good stuff. It is maybe 5% weaker than Pyro RS, but it shoots REALLY clean - cleaner than ANY other powder on the market. I used it until 777 came out. And the reason I switched is because CleanShot is VERY prone to moisture degradation. I had a partial bottle of it go bad literally overnight. One day it shot fine & the next it was all over the page............and I always keep my powders indoors, under air.
I still have an unopened bottle.....holding it ready for a Non-rainy day
