The original light-bullet load for the .375 H&H, a 235-grain softnose at 2,800 fps, is long dead. Modern 260-grain bullets beat it ballistically with better terminal performance. A 260-grain Nosler AccuBond delivers more punch at 200 yards than a 180-grain .30-06 bullet musters at the muzzle, and flies just as flat. It may well supplant traditional 270-grain softpoints in the .375. Most development recently has focused on heavy bullets; the field of 300-grain loads is rich indeed. Few 300-grain bullets for tough game are sleek in profile, but they have great sectional density, and trajectories flat enough for a 200-yard zero. Here are two fine factory loads that bracket the practical bullet weight range for the .375.
Handloading the .375 is easy, and the cartridge seems forgiving–most loads stoked to hunting speeds shoot accurately. Not long ago I unearthed a box of mild 300-grain loads I’d assembled 28 years ago. Before hunting, I shoved a handful in the magazine of my Montana rifle. The first two holes at 100 yards touched. Prairie dog accuracy from a dangerous-game rifle!
You needn’t handload for top performance, though. The .375 is blessed with factory loads for every task. Remington offers 300-grain Swift A-Frames and, with Barnes now in the Freedom Group, should add TSX bullets. Winchester lists 300-grain Nosler Partitions and Solids; Hornady catalogs five .375 loads, with 270-grain softpoints, 300-grain softs and solids. Hornady’s Superformance ammunition tops the velocity charts, giving the .375 nearly 5,000 ft-lbs of energy on exit.
Federal trumps competitors with the widest selection of 300-grain loads listing Barnes, Swift and Trophy Bonded expanding bullets and two excellent solids. Norma offers a 270-grain TSX load, plus 300-grain Oryx and Swift A-Frame options. In addition, Norma’s African PH line carries 350-grain softs and solids from Woodleigh. I can’t think of better bullets for the .375 than those five. If you want custom-loaded ammo, you can supply the recipe to Superior Ammunition–or ask Larry for his considered opinion. Safari Arms also loads custom cartridges. Like Superior, it makes a beautiful product. A typical first package has four loads of five rounds each, so you can test and compare economically, then get more of the top load
