I have used three of Ramshot powders. The first was Enforcer. The manual had some .45ACP loads pushing a 230gr bullet at 1078fps at standard presser. I worked up a load that got me 1028fps. I did not like it in the .357mag. In the .44mag I found a load with a 240gr LSWC that gives me 1220fps that shows some promise. I found True Blue to be a disappointment so far. Tac shows some promise in .223rem. Good velocity and accuracy, need to work with it some more. I wish Ramshot would get some more data out.
