I would like to take my .375 to HartzView next year with Eland being on the menu. I had some of these leftover from trying to develop rounds with IMR4350. I never had the luck with that powder in that bullet weight that I had with the 300gr loads. After some web scouring, it seemed RL15 was good for the lighter bullets in this caliber. Max load per the manual is 71.5gr and this was the most accurate. The .375 holes are as follows. Top left is from 2 shots and the one directly below it is the 3rd. The other 3 holes to the right and lower are from my .300WM.
