I finaly got my 338-325 WSM done and all I can say is WOW! If anyone else has one I'd like to share load data. I used a 700 long action, Lilja 28" barrel 10 twist in a sendero stock. I used Quickload to find a starting point. Then worked up. I was hoping to use H1000 as my 6.5 WSM loves it. I settled on 7828,RL25, and RL22. 7828 was the slowest at 2550fps @ max load. The RL22 was 2574fps with a es of 6fps. At this point I was happy as three shots looked like a perfect little 3 leaf clover measuring 5/8" outside to outside. All that was left was the RL25. In the end 72gr RL25(compressed load) 2650fps with the 300gr Hybrid that would print 3 shot groups in the 3's. For a short mag it would sure give the 338 RUM a run for it's money with a lot less powder.
