[QUOTE="dougduey, post: 1157788, member: 33159"] I have a Sako 75 in 300 WSM. 24" barrel with 1:11 twist. It shoots Winchester Supreme 180 Accubonds very well, but Winchester stopped making them so I had to start reloading. It's been fairly easy working up very accurate hand loads for this weapon. The recipes listed are all sub moa and 0.80" at the most. Velocities listed were done over a Magnetto speed chrono. The WSM performs best with ball powders for the most part, and is what is suggested in most of the data I've read. 180gr Accubonds. All with WLRM primer and Nosler brass 65.5 HV100 2.86 OAL 3095 fps 0.304" group (most accurate load) 66.8 W-760. 2.86 OAL. 3081 fps 0.494" 66.0 RL17. 2.86 OAL. 3101 fps. 0.522" 69.5 RL19. 2.86 OAL. 2965 fps. 0.488" 180gr Partition. Same primer and brass as above 65.5 HV100. 2.86 OAL 0.427" group. No chronograph data 180gr E-Tip. Same primer and brass 64.5 HV100 2.80 OAL 3022 fps 0.824" group 180gr TTSX. Same primer and brass 64.5 RL17. 2.90 OAL 3009 fps. 0.714" groups 200 gr Accubonds. Same primer and brass 62.8 RL17. 2.90 OAL. 2909 fps. 0.694" groups I just bought a box of the 200 gr Hornady ELD-X. I'll post my results after I work up a good load or two. Good luck. [/QUOTE]
