I just got a Tikka T3 stainless in 300 WSM (mine was not a recall BTW). It has a 1 in 11 twist, and I plan on shooting 165 or 180 grain bullets with it. I have 165 grain HPBT sierra GAMEKINGS and 180 grain BTs and accubonds on hand. For powders I have lots of IMR 4350, H4831SC, and RL 22. I don't care as much about velocity as I do about accuracy. What in your opinions would be a couple of my best powder choices (whether I have the powder or not) to test first? Of course i don't know how much time I will have to work up loads since I just got my 300 win mag back from the smith. This time I put a 28" #5 contour broughton 5C 1 in 11" twist on it and had the bolt sleeved and action glass bedded (everything was already trued, trigger lightenned,and pillar bedded stock put on it from the time I had the shilen put on it).
