Thanks for sharing your results. I'm still trying to get Hornadys to shoot out of my 338 Federal. I might stop trying to find a load for the SST based on your results. In general, do you find your groups are better when COL is longer? I started at 2.82 but am starting to move it out. I just loaded some SST and Interlocks to 2.86 and will test tomorrow. I also ordered 2 boxes of Partitions seconds. I'm glad I'm not the only one that couldn't get the 215 Sierra to expand out of the Federal. That is one tough bullet.
I'm using TAC and 2230. Any good recipes for either of those powders?
