There are a lot of ways to approach this topic. I’ll try one I haven’t done before. I’m talking about the four common smallbore calibers – .177, .20, .22 and .25.
What is .177 caliber good for?
For starters, .177 caliber is the official caliber for world-cup and Olympic target competition. No other caliber is legal. I also explained why .177 is the only competitive caliber for field target, though any caliber can be used. Seventeen-caliber pellets are the least expensive, so if you plan to do a lot of general shooting and plinking, this is the caliber to get. Some airguns don’t give you a choice. The Umarex action pistols (Walther, Beretta,
Colt, Desert Eagle and S&W, for example, come only in .177. Crosman’s 1077 rifle, a 12-shot repeater, is also a .177 exclusive.
