How to Choose the Right Rifle for Mountain Lion Hunting?

April 5, 2026

Quick Answer

For mountain lion hunting in Utah, choose a rifle with a caliber between 243 and 308 Winchester, chambered in a rifle with a minimum 22-inch barrel and weighing around 7 pounds. The rifle should also have a suitable scope for medium to long-range shots. Consider a bolt-action rifle for its reliability and accuracy.

Caliber Selection

When selecting a caliber for mountain lion hunting, consider the distance at which you will be shooting. In Utah, mountain lions are often taken at medium to long ranges, so a caliber with sufficient kinetic energy to penetrate the animal’s body is essential. The 243 Winchester, with its 100-grain bullet, provides sufficient kinetic energy at 300 yards, while the 308 Winchester, with its 150-grain bullet, offers even more penetration. A 243 or 308 Winchester rifle is an excellent choice for mountain lion hunting in Utah.

Rifle Barrel Length and Weight

A minimum 22-inch barrel is recommended for mountain lion hunting. This length allows for sufficient accuracy and stability, even when shooting at longer ranges. A rifle weighing around 7 pounds is also desirable, as it provides a comfortable shooting platform without being too heavy to carry throughout the day. When choosing a rifle, consider the balance between weight and length to ensure a comfortable shooting experience.

Scope Selection

When selecting a scope for mountain lion hunting, consider a scope with a 3-9x or 4-12x magnification range. This range provides sufficient magnification for medium to long-range shots while maintaining a wide enough field of view to quickly acquire targets. A scope with a 1/8-inch MOA click value is also recommended, as it allows for precise adjustments to the reticle. A scope with a durable lens coating and a waterproof design is also essential for withstanding the rigors of hunting in Utah’s mountainous terrain.
