Is there a significant difference in recoil between 300gr and 405gr .45-70?

Bullet Weights and Their Impact on Recoil

The .45-70 is an old cartridge that’s known for its potent recoil, and the choice of bullet weight plays a significant role in this. A 300gr bullet has a muzzle energy of around 2,900 ft-lbs, while a 405gr bullet can have up to 3,800 ft-lbs of muzzle energy. This increase in energy translates to a significant increase in recoil, especially for larger game like elk.

Measuring Recoil

To put these numbers into perspective, consider that a 300gr .45-70 load typically has a recoil impulse of around 25 ft-lbs, while a 405gr load can have up to 35 ft-lbs of recoil. This increase in recoil impulse can be felt by the shooter, particularly in larger rifles or those with a longer barrel. To mitigate this, shooters can consider using rifles with a heavier stock or a muzzle brake to reduce the felt recoil.

Recoil Reduction Techniques

For those who plan on hunting with the .45-70, it’s essential to be prepared for the recoil. Here are a few techniques to help reduce the impact of recoil:

• Practice shooting with a light load to build up your stamina and get accustomed to the rifle’s recoil.
• Use a rifle with a muzzle brake or a compensator to redirect the gases and reduce the recoil.
• Choose a rifle with a heavy stock, such as a laminated or fiberglass stock, to help absorb the recoil.
• Consider using a recoil pad or a shock-absorbing pad to reduce the felt recoil.

By understanding the impact of bullet weight on recoil and using the right techniques, shooters can effectively manage the recoil of the .45-70 and enjoy a more comfortable hunting experience.
