    I will be working up loads for my 300 ultra using the 220gr SMK bullet. will be using H-1000. I was going to use load data provided by Accurate reloading website for this combo but noticed that their loading was quite a bit higher than what I already had for this combination (88.0-91.0 grains). does anyone use this data or know if it is safe? they were load testing in the same rifle I have (sendero) and had excellent accuracy.
