How to Choose a Varmint Rifle

Choose a varmint rifle based on intended range, target size, and shooting conditions. Prioritize accuracy, flat trajectory, and manageable recoil for rapid follow-up shots on small, fast-moving targets.
How This Affects Your Build
Varmint rifles serve a specific role requiring precision at moderate to long ranges against small targets like prairie dogs, groundhogs, and coyotes. The demands differ significantly from hunting larger game, emphasizing rapid target acquisition and consistent shot placement over stopping power.
The Detail
Your cartridge selection drives everything else about the rifle. Popular varmint cartridges like .223 Remington, .22-250, and 6mm variants offer excellent accuracy with relatively flat trajectories out to 400 yards. The .223 provides economical shooting with manageable recoil, while the .22-250 extends effective range but increases barrel heating concerns during extended shooting sessions.
Barrel considerations become critical for varmint work. Heavy contour barrels resist heat buildup better during rapid firing sequences common in prairie dog towns, though they add significant weight. Barrel length affects both velocity and handling, with 20 to 24-inch barrels providing good balance between performance and maneuverability. Stainless steel barrels often prove more durable in harsh field conditions.
Optics selection requires balancing magnification with field of view. Variable scopes in the 4-16x range handle most varmint scenarios effectively, providing enough magnification for precise shot placement while maintaining sufficient field of view for target acquisition. Quality glass becomes essential when shooting in varying light conditions typical of early morning or late evening varmint hunting.
Stock design affects both accuracy and field usability. Heavy, rigid stocks improve accuracy from shooting benches but become cumbersome for field carry. Adjustable cheek risers help achieve consistent sight picture with higher-mounted scopes typical of varmint rifles. Consider how much walking versus stationary shooting your typical varmint hunting involves.
Build Impact
If building an AR-15 for varmint work, you'll want a heavy barrel profile and quality trigger to maximize accuracy potential. Consider a rifle-length gas system to reduce bolt velocity and improve consistency with lighter varmint bullets.
