Shooters World is the U.S. brand name of Lovex made powders. Both of those have published data on the internet.
I have not used any of them. I looked at their load data in my calibers, and it was on par with powders I have on hand (Power Pistol, Silhouette, Bullseye, Unique, BE-86, Longshot). So, no compelling performance gain. Costs were typical, and less than VV.
