This video details a ballistics test comparing a .44 Magnum round to a 1.2 lb Parrott rifle projectile fired into 38 inches of ballistics gelatin and plywood. The expert analysis highlights the significant energy transfer and projectile deformation of the cannon round, providing unique data on historical artillery performance.

Quick Summary

A Parrott rifle cannon projectile, weighing 1.2 lbs, delivered an estimated 45,000-46,000 ft-lbs of energy into 38 inches of ballistics gelatin and plywood baffles. This demonstrated significantly greater destructive power compared to a .44 Magnum round, with the cannon projectile deforming its Minié-style skirt to engage rifling.

Frequently Asked Questions

What is the energy output of a Parrott rifle projectile compared to a .44 Magnum?

The Parrott rifle projectile tested delivered an estimated 45,000-46,000 ft-lbs of energy. While the specific energy for the .44 Magnum load wasn't directly stated in ft-lbs, its impact was significantly less destructive than the cannon round, indicating a much lower energy level.

How does a Minié-style projectile work?

A Minié-style projectile, like the one fired from the Parrott rifle, features a hollow base. Upon firing, the expanding gases force the skirt of the projectile to deform and engage the rifling, ensuring spin for stability and accuracy.

What was the setup for the ballistics gel test?

The test involved 38 inches of ballistics gelatin followed by 12 three-quarter-inch plywood baffles. This setup aimed to measure the penetration and energy transfer of both the cannon projectile and the .44 Magnum round.

What happened to the Parrott rifle projectile after impact?

After impacting the ballistics gel and plywood, the 1.2 lb Parrott rifle projectile deflected downward, penetrated three wooden pallets, and buried itself approximately 10 inches into the dirt backstop.
