A little late to the thread, but I was happy to see a vote for 760.
I'm new to the 375, but ended up with 2. Initial reloading efforts were with the 300 Sierra, since that was all I could find at the time. Based on Ken Water's recommendations, tried 760 as part of my initial testing, and got better results than with RL15, Big Game, or 4350. 77.5 - 760 at about 2600 dropped immediately into 1" groups with the RSM, and the M700 liked it just as well. POI is right with factory ammo as well - good stuff! Looking forward to trying the 270s next.
PS - it may be awhile before I can try RL 16 or 17, as powder and primers are now unobtainium!
