Cannonball vs Hollow Point for Groundhog Hunting — Which to Use?

April 5, 2026

Quick Answer

For groundhog varmint hunting, I recommend using a hollow point bullet, specifically a .22 caliber or .223 Remington, as it provides the most effective expansion and penetration for quick and humane kills.

Choosing the Right Ammunition

When it comes to groundhog hunting, selecting the right ammunition is crucial. A hollow point bullet is ideal for varmint hunting, as it expands upon impact, creating a larger wound channel and increasing the chances of a quick kill. In contrast, a solid bullet like the cannonball, while effective for larger game, may not provide the same level of expansion and may not be as humane for smaller game like groundhogs.

Caliber and Velocity Considerations

For groundhog hunting, a .22 caliber or .223 Remington is a popular choice, and for good reason. The lower velocity and smaller diameter of these cartridges make them ideal for hunting smaller game, while still providing enough kinetic energy to ensure a quick kill. Aiming for a velocity of around 2,500-3,000 feet per second will provide the best balance between expansion and penetration. Additionally, using a bullet with a jacket-to-core ratio of around 50:50 will help ensure consistent expansion and minimize the risk of over-penetration.

Practical Application

When hunting groundhogs, it’s essential to remember that accuracy and follow-through are just as important as the type of ammunition you’re using. Take your time, aim for a spot just behind the ear, and follow through with each shot. For close-range shots, consider using a scope with a 2x-4x magnification to help you quickly acquire your target and make accurate shots.
