so I've had this rifle for sometime and finally got around to doing load development. Needless to say it didn't like any powders besides rl26. Tried h1000, retumbo, imr 8133... with no good results. I'm shooting 143gr eldx's. Anyways I thought I'd just post this in here if anyone else is looking for 6.5wsm info. Started at 60-65grs of rl26 and hit pressure at 63gr. Then did from 61.6-62.8 and found 62.6 is going to be the best for my gun.... speed was 3110fps out of a 24" with the suppressor on.
