CCI 3740B .40 S&W Shotshell Ammunition - 10 Rounds per Box, 20 Boxes per Case

CCI 3740B .40 S&W shotshell ammunition delivers a specialized, lead-free option for shooters tackling pest control at close range. Built on CCI's time-tested centerfire handgun shotshell design, these rounds pack HEVI-Bismuth pellets—a non-toxic shot material alloyed and cast in Sweet Home, Oregon—that delivers density and downrange energy comparable to traditional lead. With a Catalyst lead-free primer and Size 8 shot, this ammunition is engineered for controlled, effective patterns on varmints and problem wildlife in scenarios where standard centerfire rounds aren't the right tool.

The HEVI-Bismuth formula hits 9.6 g/cc density, allowing it to maintain energy and penetration downrange despite being completely lead-free. That matters whether you're managing property in lead-restriction zones, hunting where non-toxic shot is mandated, or simply choosing ammunition that aligns with your environmental values. Each box contains 10 rounds, and you can purchase by the case (20 boxes) for consistent supply.

These aren't general-purpose self-defense rounds—shotshells in a .40 S&W platform are specialized varmint tools. The 1300 feet-per-second muzzle velocity and shot-style design make them effective for close-quarters pest work. If you regularly encounter problem animals on your property and need a lead-free, pattern-controlled solution that your .40 platform can deliver, CCI's shotshell line fills a specific niche few manufacturers bother to address.

Frequently Asked Questions

What is .40 S&W shotshell ammunition used for?

CCI shotshells in .40 S&W are designed for close-range varmint and pest control—scenarios where controlled shot patterns and minimal over-penetration matter. They're not practical for hunting game or general defensive use; they fill a specific niche for on-property pest management.

Is this ammunition lead-free?

Yes. These rounds use HEVI-Bismuth shot, which is completely lead-free and complies with non-toxic ammunition regulations. The Catalyst primer is also lead-free, making the entire cartridge non-toxic.

How does HEVI-Bismuth compare to traditional lead shot?

HEVI-Bismuth pellets achieve 9.6 g/cc density, which provides nearly the same downrange energy and penetration as lead shot despite being a different material. This allows lead-free performance without sacrificing effectiveness at typical varmint ranges.

What does a case of 20 boxes contain?

A case includes 20 boxes of 10 rounds each, for a total of 200 rounds. This case quantity is useful for regular shooters and property managers who rely on shotshell varmint control.
