.22 vs .25 Air Rifle: Which Should You Choose?

For hunting and pest control, the real caliber debate isn’t .177 or big bore — it’s .22 versus .25. Both are excellent. They just lean different ways, and which one wins depends entirely on what you do with it.

The case for .22

The .22 is the efficiency champion. It carries plenty of energy for rabbits, squirrels, and rats, shoots flat enough for easy holdovers, and sips air — so you get more shots per fill and more forgiving range estimation. Pellet choice is vast and cheap. For general hunting and high-volume pest control, .22 is hard to beat.

The case for .25

The .25 trades efficiency for authority. The heavier projectile hits harder, transfers more energy on impact, and resists wind better at distance — which matters on bigger pests, tougher quarry, or longer shots on a breezy day. The cost is air: fewer shots per fill, and the rifle works harder. On a regulated platform that runs it well, .25 is a deliberate, decisive choice.

Head to head

• Shot count / air efficiency: .22 wins.
• Downrange energy & wind resistance: .25 wins.
• Trajectory / ease of holdover: .22 a touch flatter.
• Ammo cost & selection: .22 cheaper, more options.
• Bigger quarry / longer range: .25.

So which?

Pick .22 for all-round hunting and lots of shooting. Pick .25 when your quarry runs bigger or your shots run longer and windier. Neither is a mistake. For the full picture across all calibers, read the air rifle caliber guide, then browse air rifles.
