More new powders?! Even gunwriters are being over come with the number of gunpowders on the market, Charles Petty had 12 powders he could use in a 45 ACP article, which was far too many, so he cut the number down to three. I think it was three.
I am going to wait till others use and test and some load combinations become well established through the process of survival of the fittest. Such as what has happened for Varget, Titegroup, Power Pistol. These powders have shown themselves to be excellent choices for their applications.
