How to Select a Bullet PART I

Published on February 24, 2016
Duration: 46:30

This video delves into the critical concept of sectional density for selecting effective rifle bullets, particularly for deer hunting. The instructor explains that sectional density, a ratio of weight to diameter squared, is a primary driver of a bullet's penetration capability. He emphasizes that traditional knowledge and experience are vital, often found in handloading manuals, which provide data on sectional density, ballistic coefficient, and intended use. The video provides specific sectional density benchmarks for various calibers to ensure reliable performance.

Quick Summary

Sectional density is a critical factor in bullet selection, representing a bullet's weight relative to its diameter squared. Higher sectional density indicates greater penetration potential, essential for effectively reaching the vitals of game animals like deer. For 30 caliber bullets, aim for at least 0.226, with 0.242-0.253 being ideal. Consult handloading manuals for specific data.

Frequently Asked Questions

What is sectional density and why is it important for bullet selection?

Sectional density is a measure of a bullet's weight relative to its diameter squared. It's crucial because it directly influences a bullet's ability to penetrate targets like bone and tissue. Higher sectional density generally means better penetration, making it vital for effective hunting.

What sectional density should I look for in a deer hunting bullet?

For 30 caliber bullets, aim for a sectional density of at least 0.226, with values around 0.242 to 0.253 being ideal for reliable penetration to the vitals. For smaller calibers like 6mm or 25, a sectional density of about 0.240 is recommended.

Where can I find sectional density information for bullets?

Sectional density figures are not always printed on ammunition boxes. The best place to find this information is in handloading manuals from bullet manufacturers like Hornady. These manuals detail bullet weight, ballistic coefficient, sectional density, and intended use.

What are recommended muzzle velocities for effective deer cartridges?

For effective deer cartridges, muzzle velocities generally should be upwards of 2600 feet per second, with an ideal range between 2600 and 2900 feet per second. Velocities exceeding 2900 fps can sometimes lead to excessive meat damage.
