Sundog. I agree that the slower burning powders should not be used for reduced loads. However, IMR-4895 works well for such use. If you are not a member fo the cast bullet association, it is well worth joining up. Their magazine, THE CAST BULLET, has good data to work from. They have bench rest matches, and the load data used by these shooters is included. I looked up the data for 4895 in .308 Win. to see what worked for these shooters. I averaged the loads and used that. Velocity is about 1800 FPS and I am getting good groups. Lack of time has prevented me from working further on these loads, but I'll get to it. I get very little powder residue from these loads. Just something to think about.
