This guide details an experimental procedure to test the effect of spinning saw blades on a high-velocity rifle round. It outlines the setup using a 1903 Springfield rifle and .30-06 AP ammunition, emphasizing the use of a remote firing rig for safety. The experiment involves firing at both spinning and stationary blades to compare results, with a focus on observing bullet penetration and trajectory changes. The speaker, Edwin Sarkissian, demonstrates high authority in experimental ballistics entertainment.

Quick Summary

An experiment testing if spinning saw blades affect a rifle bullet found no significant difference. A 1903 Springfield firing .30-06 AP rounds penetrated spinning 10-inch, 40-tooth carbide blades at 6000 RPM similarly to stationary blades, with one instance of keyholing observed.

Frequently Asked Questions

Can spinning saw blades stop or slow down a rifle bullet?

In an experiment using a 1903 Springfield rifle and .30-06 armor-piercing ammunition, spinning 10-inch, 40-tooth carbide saw blades at 6000 RPM showed no significant effect on the bullet's trajectory or penetration compared to stationary blades.

What type of ammunition was used in the spinning blade test?

The experiment utilized .30-06 armor-piercing (AP) ammunition fired from a 1903 Springfield rifle. This choice was made to ensure the bullet would not easily deform upon impact with the hard surfaces of the saw blades.

What is 'keyholing' in shooting?

Keyholing occurs when a bullet strikes a target sideways, causing an elongated, keyhole-shaped impact mark. This indicates bullet instability, often due to issues with the bullet's flight path or the rifling twist rate.

How was safety ensured during the spinning blade test?

Safety was maintained by using a remote firing rig to operate the 1903 Springfield rifle from a distance, minimizing the operator's exposure to potential hazards like fragmentation or ricochets.
