The two most common are IMR/H/A4350 and RL15.

I don't shoot mine as much as I did 25 years ago, but those are the two powders I've used most in the past. I always liked the 235gr bullet (because it is only 235 grains), as well as the 300 Sierra Boat Tail because of its excellent ballistic properties. I also shot a lot of the Hornady 270gr flat base, because they were cheap(er). If I were going to be buying components today, I would probably buy Nosler Partitions.

IMR 4064 is more accurate in my experience, IMR 4350 gives you a bit more velocity. Some links:

I loaded up my 375 H&H with IMR 4064. Worked fine. I cannot remember the powder charge, but my recollection was that one pound goes very quickly.

Ramshot Hunter and Big Game do well, as does W760. My personal favorite is VV N550. 4320 and 4895 are also great, but I typically like heavy bullets.

Accordiing to QuickLoad, W760 and Ramshot Hunter should give the best velocity with a given pressure

Please shut off your caps lock. Your manual should have data. Midway, et al has brass. Midway wants $42.99 per 100 for Remington brass.

I think the best powder for the 375 H&H Magnum is probably RL-15.

At 100 yards off the bench shooting 3 shot groups, I get about 1.5 inch groups with Hornady 300 gr. BTSP bullets and less than 1 inch groups with Hornady 300 gr. FMJ round nose bullets.

Another thing about the 375 H&H Magnum; the cases tend to stretch a lot and early. Be sure to check the case length and trim as needed. Also, run a paper clip with the tip bent down the inside of the case to detect the groove that starts before head separation.

Well, you specified full-tilt-and-boogie, and 300gr bullets. Sooooo...
My biggest grin-getter was a 72gr of H4895 behind a Speer 235. Probably ~ 2600, not too unpleasant. Never shot it at game, but it would really shoot tight groups ~ 3/4" at 100. I bet it would mow down any deer and most elk.

I found that 64 grains of IMR 4064 worked best under a 300 Sierra Game King. That recipe did well on a 500+lb boar in Belgium.

Winchester 760 gave up a smidge of velocity and accuracy, but not enough to become excited - - - and was MUCH easier to meter. ;)
