This video provides a detailed look at a 10mm handload featuring 9.0 grains of Hodgdon Longshot powder and a 165gr Sig Sauer V-Crown JHP bullet. An experienced handloader demonstrates the process and conducts chronograph testing through a Glock 29 (3.78-inch barrel) and a 1911 (5-inch barrel), yielding velocities of 1225 fps and 1325 fps respectively. The data highlights the impact of barrel length on ballistic performance.

Quick Summary

A 10mm handload using 9.0 grains of Hodgdon Longshot powder and a 165gr Sig Sauer V-Crown JHP bullet was tested. It achieved 1225 fps from a 3.78-inch Glock 29 barrel and 1325 fps from a 5-inch 1911 barrel, demonstrating the impact of barrel length on ballistics.

Frequently Asked Questions

What are the components for the 10mm handload tested in the video?

The video tests a 10mm handload consisting of 10mm brass, 9.0 grains of Hodgdon Longshot powder, and Sig Sauer 165gr V-Crown Jacketed Hollow Point (JHP) bullets. A digital scale is used to ensure the precise powder charge.

What velocities were achieved with the 10mm Longshot load?

The 10mm handload achieved a velocity of 1225 feet per second (fps) when fired from a Glock 29 with a 3.78-inch barrel. Firing the same load through a 1911 with a 5-inch barrel resulted in a higher velocity of 1325 fps.

How does barrel length affect the performance of this 10mm load?

The chronograph data shows a noticeable difference based on barrel length. The longer 5-inch barrel of the 1911 produced 100 fps more velocity and 93 foot-pounds more muzzle energy compared to the 3.78-inch barrel of the Glock 29.

What muzzle energy was calculated for the 10mm handload?

From the Glock 29 (3.78-inch barrel), the 10mm load generated approximately 550 foot-pounds of muzzle energy. From the 1911 (5-inch barrel), the muzzle energy increased to approximately 643 foot-pounds.
