Quick Answer
For accurate .357 Magnum lever gun shooting, typical group sizes range from 2-4 inches at 100 yards, depending on the rifle, ammunition, and shooter skill. A well-tuned rifle with a competent shooter can consistently achieve tighter groups. With practice and the right tools, groups can be reduced to 1.5-2 inches or smaller.
Lever Gun Performance Factors
When evaluating group sizes for a .357 Magnum lever gun, several performance factors come into play. To achieve tight groups, it’s essential to match the rifle’s chamber throat and barrel with the correct cartridge and bullet type. A good starting point is to load the rifle with 158-grain JHP or full-jacketed bullets, which provide the right balance between expansion and penetration for deer hunting.
Rifle and Ammunition Selection
The selection of the right rifle and ammunition is crucial for achieving tight groups with a .357 Magnum lever gun. For example, the Thompson/Center Encore Pro Hunter features a 1:18.75-inch twist rate, making it an excellent choice for 180-grain bullets. When pairing the rifle with the correct ammunition, consider a cartridge with a longer overall length to ensure proper feeding and extraction.
Shooting Techniques and Tips
To achieve the best possible group sizes, shooters should focus on proper rifle handling, stance, and breathing techniques. A consistent shooting stance, with the rifle supported by a bipod or shooting sticks, can help reduce movement and improve accuracy. Additionally, take time to zero the rifle and practice at longer ranges to build confidence and develop muscle memory.
