I just purchased my first 375, any advise on loads or other wise would be much appreacieated.

Get the latest Nosler manual (should be out soon) and start with RL15 per the manual..probably the best powder for the H&H. If you don't like it the next best is Varget.

73 gr RL-15 behind a 260 gr nosler partition, remington brass and fed 215 primer, col 3.600" gives me 2740 fps and good accuracy out of my M70.

I agree with DB Bill as to trying RL-15 and Varget and also IMR-4320. One of these will satisfy you, especially with the 270 & 300 grainers.

Varget is anice powder to work with and is supposed to be temperature stable. I've had good results in my 9.3x64

And don't overlook that RL-19 behind the 300+ grain bullets.

RL-15 is my powder of choice for the 375 H&H.
