14.5" 6.5 Creedmoor out to 1220 yards

Published on June 15, 2024
Duration: 11:13

This video explores the capability of a 14.5-inch 6.5 Creedmoor AR-10 style rifle for long-range shooting, specifically out to 1220 yards. The presenter, while not a professional long-range shooter, demonstrates the rifle's effectiveness using Hornady 147-grain ELD-M ammunition and a Maven RS.12 scope. Key takeaways include the challenges of the transonic threshold, the importance of accurate velocity data for ballistics calculations, and the impact of target size on hit probability at extreme distances.

Quick Summary

A 14.5-inch 6.5 Creedmoor rifle can achieve hits at 1220 yards, but it's not ideal. Factors like the transonic threshold and scope limitations are challenges. For such distances, ammunition with a high Ballistic Coefficient, like Hornady 147gr ELD-M, is recommended. Velocity can be estimated using ballistics calculators if a chronograph isn't available.

Frequently Asked Questions

Can a 14.5-inch 6.5 Creedmoor rifle shoot accurately at 1220 yards?

Yes, a 14.5-inch 6.5 Creedmoor rifle can technically achieve hits at 1220 yards, as demonstrated in this video. However, it is not an ideal configuration due to factors like the transonic threshold and limited scope adjustments. Longer barrels offer better performance at extreme distances.

What ammunition is recommended for a short-barreled 6.5 Creedmoor for long-range shooting?

For a short-barreled 6.5 Creedmoor intended for long-range, ammunition with a high Ballistic Coefficient (BC) is recommended. The Hornady 147-grain ELD-M is a good choice due to its BC, which helps maintain velocity and stability at extended distances.

How can you estimate bullet velocity without a chronograph?

You can estimate bullet velocity by using a ballistics calculator with known distances and observed impacts. By inputting your ballistic data and adjusting the velocity input until the calculator's output matches your real-world results, you can derive a reasonable velocity estimate.

What are the challenges of shooting at the transonic threshold?

Shooting at the transonic threshold, where a bullet transitions from supersonic to subsonic speeds, presents significant challenges. Bullets in this phase can become unstable, leading to unpredictable flight paths and a reduced chance of accurate impacts.
