I just started working with a friends 300 wsm in a sako 75. The first load we tried was 67 of h414 under a 150 partition gold moly. (The ones Midway was selling a while back in bulk for $4.99/50). We went to the range....got his scope adjusted.....and proceded to shoot a 5 shot 1" group at 100yds. Speed was 3051fps. I loaded a few other recipes but we didn't get to them that day. I'll be watching to see what others have to say here but it was fun "catching a good load" right off the bat with the above load. Also.....I was impressed with speed consistancy of this load....most every shot was within 10 fps of each other.

I have had some good luck with the 155 gr Bergers on top of 68 grain of W760 with Win Mag primer. 3168 averave velocity. 1/2 to 3/4 inch at 100 but great at 5, 6, and 700. I am shooting them through a Howa sporter with the laminated thumbhole (bedded of course) definately needs a new trigger. Hope this helps.
