I looked in my Lyman 49th edition, the Lee manual, and the Lyman cast bullet handbook but cannot find data I am looking for. I have a 230 grain bullet for my Winchester that I am wanting to load. I am aiming for 2100-2200 fps. The powder I was going to start with was the 3031. I was thinking of starting at the 36 grain mark and working up. Any reason that won't work? I also have Win 748, IMR 4064, and Reloader 19, powder on hand if anybody has a good load they would be willing to share utilizing these powders. I was steering away from the 748 because I don't know about the temp stability on that, but maybe I should try it!
