Here is some info I came up with in the process of trying to develop a practice round that simulates my carry round. When I pulled a Black Hills standard pressure round apart to see what and how much powder it used, I was surprised to see it look just like Power Pistol. After weighting the powder and comparing the chrono data to what I had used in developing loads with Power Pistol, it pretty much confirmed it was Power Pistol. Also, as seen in the pictures, the bullet used by Black Hills looks to be Hornady
