    A few years ago I bought a 375 HH because I was heading on a safari and wanted an "Afirca gun" even though I wasn't hunting dangerous game (and sold a perfectly good 338 win to get it :( ). It shoots reasonably well and I can handle the recoil but it's far from fun, and down right unbearable after about 15-20 rounds. The rifle is a synthetic model 700 and only weighs about 7lbs which is wonderful for packing but like I said takes all the fun out of shooting it. I bow hunt elk and have a wonderful load for my '06 that puts 5 Partitions into sub MOA groups at over 2800fps so I really don't need the 375 but can't bring myself to sell it due to its sentimental value after taking it to Africa. I was thinking about developing a load that would throttle it WAY back to the "fun" realm but keep it able to still flatten anything I point at it. I'd like it to keep a 250-270 grn bullet inside of about 2.5" at 100yds without it having the trajectory of a rainbow. All the reloading manuals/tables I've seen have loads in the near to the same ranges or higher than the factory ammo. What would be a good starting point for a load as I described? Or is this all a pipe dream trying to make this cartridge something it's not?

    I have some RL 19, 22 and 25, lots of Hunter and a couple pounds of IMR and H4350 to choose from...

    Any and all advice is appreciated!

    Muzzle break, Soft butt pad and full house loads. That's what I'd do....

    Owned a 9.5# Bruno 602 in .375 H&H for 20 years. My only rifle in fact for many years.

    An elephant gun--> 300gr full velocity loads=>> will give you a concussion.

    Good technique sitting or standing ----> easy as a .308 to shoot well. The 300 grain ballistic curve, is that of the .308, pretty much.

    But you will get that serious concussion headache by 20 rounds. Don't do it.

    I hand-loaded most of the time, and one of the things to really be aware of is light loads can be high pressure loads. With such a big case. be very careful not to go below the lower powder limits, suggested by the powder maker. Bad things can happen.

    In practice I would rather suggest that you restrict your shooting to 8-10 rounds per session. That concussion that moves through your jaw is unavoidable. It's not the recoil. It's the shockwave. No amount of double earplug/muffs can help mitigate that bone conducted shockwave that violently bangs your brain. A brake helps not at all with this - (maybe worse). In the allowable powder range I tried, the lower limit didn't help the shockwave a lot. :D

    Elephant guns - the real contact sport!
