Works nice in the 3006 165 gr in my 03A3, 03 , & 1917 rifles just follow the data from Hodgon's manual. There are powders that could be more perfect or give greater accuracy and velocity. I don't know. You can spend a fortune searching them out and developing them. I started with a 1 lb bottle to try it. I like it so far and have a 8lb jug it cost me 169+12tax=181÷8= $ 22.60 /lb that's inexpensive shooting in my book. What do you want ,egg in your beer? MB
