Buffalo Bore’s rifle cartridges that are intended for use on Dangerous Game are full-powered, but we do NOT try to milk every extra FPS out of them as we would prefer to have low pressures that leave room for bad circumstances such as a barrel with rainwater, dust, or other debris in it. There is no good reason to have pressures so high as to cause function issues with your rifle under dangerous or adverse/sloppy conditions. This load is SAAMI compliant.

We could achieve more FPS from this load, simply by adding more powder and compressing it with the seated bullet. I do not believe in heavily compressed powder charges with dangerous game ammo, so this load is slightly compressed, but not heavily compressed.

This is our 270 gr. Solid, FN, Lehigh Defense bullet, for use on those bad angle shots of a charging or running away wounded Buffalo or an elephant brain shot. If you want super deep straight line penetration from your 375 H&H, this is the load. It will penetrate several feet through mammalian muscle and bone.

At 150 yards, this load also shoots very close to the same point of impact as our Item 54C, which utilizes the expanding Barnes TSX, 270 gr. bullet. We prefer a 270 gr. solid for deep penetration over traditional 300 gr. solids.

The American gun industry has been duplicitous in claiming bullet velocities. It’s typical for ammo companies to use very long machine mounted test barrels to get very high velocities, but in the real world, with real firearms, you simply will not achieve those results. 23-years ago, Buffalo Bore started to publicly expose this practice and today we are starting to see a few ammo companies get honest with velocities by using real-world guns to generate published velocities. About 35 years ago, (long before I was Buffalo Bore Ammunition) I bought my first chronograph as I had a deep interest in ballistics. (this is being written in 03-2020) I was immediately stunned by how low ACTUAL velocities were, versus published velocities, when it comes to the big ammo companies’ products. When I started Buffalo Bore Ammunition, I chose not to be dishonest regarding published velocities.

➤  2,851 fps -- Encore, 28 inch barrel
➤  2,746 fps -- CZ Mod. 550, 25 inch barrel
➤  2,749 fps -- Ruger # 1, 24 inch barrel
➤  2,759 fps -- Kimber Talkeetna, 24" barrel
➤  2,620 fps -- Mauser MK X, 19 inch barrel

NOTE: We started making 375 H&H ammo many years before we came out with our “Dangerous Game” loads in various rifle calibers. (375 Ruger, 416 Ruger, 416 Remington, 458 Win. Mag. and 458 Lott) Rather than change the name and item #’s of our established 375 H&H loads and confuse our distributors/customers by changing those item numbers, we’ve chosen to leave these item numbers as they were when we introduced these 375 H&H loads many years earlier. While these loads are true Dangerous Game loads, designed for African and Alaskan game animals, we simply have not included the common term of “Dangerous Game” into the name or item numbers.
