Looking to understand the real hitting power of your 10mm Auto? This hard-hitting handgun round has earned its reputation as a serious defensive caliber, and we've mapped out exactly how it performs. Using a full-power 180-grain load pushing 1,230 fps, this trajectory chart shows you what to expect whether you're carrying for bear defense in the backcountry or need precise shot placement at the range.

The default setup uses a practical 25-yard zero, which gives you a solid foundation for both defensive and hunting scenarios. But we know 10mm Auto loads can vary widely - from milder personal defense rounds to heavy-hitting hunting loads that'll stop a charging bear. That's why we've made this calculator fully customizable. Hit the "Modify Calculation" button below to punch in your specific load data and shooting conditions. You can account for everything from wind and shooting angle to environmental factors like altitude and temperature.

Whether you're sizing up your defensive loads or working up a hunting setup, these calculations will show you exactly what your 10mm can do. After all, when you're carrying a round this potent, it pays to know your holdovers.
