Best Calibers, Firearms to Use, and Safe Shooting Practices
When it comes to fast, effective pest control, CCI Shotshell Ammunition is a proven tool for eliminating snakes, rats, and other nuisance animals at close range. Whether you’re protecting a chicken coop, clearing a shed, or handling varmints on rural property, CCI shotshells provide the perfect balance of performance and safety—if used correctly.
In this guide, you’ll learn which calibers are available, the best firearms to pair them with, and how to use them safely and effectively.
🎯 What Are CCI Shotshells?
CCI Shotshells (also known as “snake shot” or “rat shot”) are cartridges filled with tiny pellets (typically #9 or #12 shot) rather than a single bullet. These rounds turn your pistol or rifle into a mini shotgun, designed for close-quarters pest control—generally within 10 to 15 feet.
Each round is topped with a plastic capsule that holds the shot together as it leaves the barrel, then breaks apart mid-flight to disperse the pellets in a spread pattern. This design minimizes over-penetration and reduces the risk of ricochets in tight environments like barns or sheds.
🔫 Best Firearms for CCI Shotshells
While CCI shotshells are offered in both rimfire and centerfire handgun calibers, not all firearms handle them equally. Here are some tips for optimal performance:
✅ Revolvers – Best Choice
- Why: No cycling issues, perfect ignition.
- Calibers: .22 LR, .38 Special/.357 Mag, .44 Special/Mag, .45 Colt.
- Best For: Pest control in rural or agricultural settings.
⚠️ Semi-Auto Pistols – Use with Caution
- Why: Many semi-autos will not cycle reliably due to low recoil impulse.
- Workaround: Manually rack the slide between shots.
- Calibers: 9mm, .45 ACP, 10mm, .40 S&W.
❌ Avoid in Ported Barrels or Compensators
- The plastic capsule may break up prematurely or clog ports, leading to unsafe firing conditions.

🛡️ Best Practices and Safety Tips
1. Wear Eye and Ear Protection
Even though these are “light” rounds, they still fire with a loud report and debris potential—especially indoors or near hard surfaces.
2. Watch the Backstop
The shot will spread quickly in a rifled barrel. Always ensure you’re firing into a safe area with no risk of ricochet or collateral damage.
3. Keep Range Close
Shotshells are not effective beyond 10–15 feet. These are close-contact rounds for fast, humane pest elimination.
4. Avoid Ported Barrels
The plastic capsule can shred prematurely or foul a ported barrel, leading to misfires or damage.
5. Know Your Laws
Always check local laws regarding discharge of firearms near structures or livestock, especially in suburban or semi-rural settings.
🧠 Final Thoughts
CCI Shotshells are an excellent solution for up-close pest control in tight spaces—whether it’s a snake in the garage, a rat in the coop, or a bird in the barn. With the right firearm and smart handling, they offer safe, targeted results with minimal risk of over-penetration.
