The Flattest Shooting Cartridges

Published on December 3, 2023
Duration: 18:20

This video compares the bullet drop of various rifle cartridges at 300 yards, revealing that the .22 Creedmoor offers the flattest trajectory among those tested. Factors like muzzle velocity and Ballistic Coefficient (BC) are crucial for flat shooting, with aerodynamic bullet design playing a significant role. The test also highlights how barrel length can affect velocity, impacting performance.

Quick Summary

The .22 Creedmoor was the flattest shooting cartridge in the Backfire channel's test. Flat shooting is primarily determined by high muzzle velocity and a high Ballistic Coefficient (BC), which relates to the bullet's weight and aerodynamic shape.

Frequently Asked Questions

What makes a rifle cartridge shoot flat?

A rifle cartridge shoots flat primarily due to a combination of high muzzle velocity and a high Ballistic Coefficient (BC). BC accounts for the bullet's weight and aerodynamic shape, indicating its ability to retain velocity and resist air resistance during flight. Higher velocity and BC mean less bullet drop over distance.

Which cartridge was the flattest shooter in the Backfire test?

In the Backfire channel's test comparing various cartridges, the .22 Creedmoor emerged as the flattest shooting. It demonstrated significantly less bullet drop compared to other tested calibers, even when fired from a rifle with a shorter 18-inch barrel.

How does barrel length affect cartridge performance?

Barrel length directly influences a cartridge's muzzle velocity. Longer barrels generally allow propellants more time to burn and accelerate the bullet, resulting in higher velocities. Conversely, shorter barrels can reduce velocity, potentially making a cartridge perform less effectively at longer ranges.

What is Ballistic Coefficient (BC) in firearms?

Ballistic Coefficient (BC) is a numerical value representing how well a bullet cuts through the air. It's calculated based on the bullet's weight, diameter, and shape. A higher BC means the bullet is more aerodynamic, retains velocity better, and experiences less wind drift and drop.
