I recently bought my first .375 H&H and I'm working on developing a hunting load for it. I'm focusing on lighter bullets, 235 and 250 grain, because I want relatively high velocity in order to obtain a relatively flat trajectory out to 350 yards. Does anyone out there load this caliber? If so, do you have any pet loads that you are willing to share?

IMHO your best bet is to purchase an adjustable case gage from L.E. Wilson. Properly sizing belted cases can be a headache and a case gage will eliminate any resizing errors that can cause you grief on a hunting trip. FWIW.
