In-depth Answer

When it comes to comparing the 340 Weatherby Magnum to the 375 H&H Magnum, the individual needs and preferences of the hunter should be taken into consideration.

The 340 Weatherby Magnum is a faster and flatter shooting cartridge, making it a good choice for longer range hunting. Its high velocity and flat trajectory make it ideal for taking shots at game at distances up to 500 yards or more. However, the 375 H&H Magnum has a larger bullet diameter and more energy, making it a better choice for hunting at closer range because of its stopping power.

Another important factor to consider when comparing these cartridges is recoil. The 340 Weatherby Magnum has a reputation for having a significant amount of recoil, which can be uncomfortable or even painful for some shooters. The 375 H&H Magnum also has a significant amount of recoil, but due to its larger rifle size and weight, it tends to be more manageable for most shooters.

Conclusion

If you want a cartridge better for longer range hunting and you can handle a lot of recoil, the 340 Weatherby is the better cartridge. If you need stopping power at close range, then the 375 H&H Magnum is the safer bet.
