CCI "Big 4" 9mm Shotshells - TheFirearmGuy

Published on April 19, 2020
Duration: 4:08

This review tests CCI's Big 4 9mm shotshells, noting their #4 shot size and 1000 fps velocity, intended for pest control. While demonstrating effective energy transfer on soft targets like soda bottles, the ammunition failed to reliably cycle a Smith & Wesson M&P 9 Compact. Pattern tests showed a surprisingly tight spread at 10 feet (around 5 inches), but significantly wider at 15 feet.

Quick Summary

CCI Big 4 9mm shotshells use #4 shot with a 1000 fps velocity for pest control. While effective on soft targets, they did not reliably cycle a Smith & Wesson M&P 9 Compact. Pattern tests showed a 5-inch spread at 10 feet, widening significantly at 15 feet.

Frequently Asked Questions

What is the intended use for CCI Big 4 9mm shotshells?

CCI Big 4 9mm shotshells are designed for pest control, specifically targeting small varmints like snakes and rats. They utilize #4 shot, which is larger than standard shotshells, and have a muzzle velocity of 1000 feet per second.

Did the CCI Big 4 9mm shotshells cycle reliably in the tested pistol?

No, the CCI Big 4 9mm shotshells did not reliably cycle the Smith & Wesson M&P 9 Compact used in the test. The reviewer suggests they are best used in manually operated firearms or as single shots due to this cycling issue.

How tight is the shot pattern for CCI Big 4 9mm shotshells at different distances?

Pattern testing showed a surprisingly tight spread of about 5 inches at 10 feet. However, the pattern became significantly wider and less predictable at 15 feet, indicating a limited effective range for consistent coverage.
