Pumping Mechanism and Power Levels
The Crosman 760 Pumpmaster Classic’s heart lies in its unique multi-pump pneumatic system. This system allows you to control the air rifle’s power by adjusting the number of pumps you apply.
Here’s how it works⁚
Pumping⁚ You pump the air rifle by moving the forestock forward and backward, compressing air into a chamber.
Power Adjustment⁚ The number of pumps directly influences the air pressure and ultimately the velocity of the projectile. More pumps mean higher pressure and greater velocity.
Variable Power⁚ The 760 Pumpmaster Classic offers a variable power range of 3 to 10 pumps. This allows you to tailor the rifle’s power to your target, from plinking at cans to taking down small game.
Important Considerations⁚
* Overpumping⁚ Never pump the rifle more than 10 times. Overpumping can damage the air rifle and potentially lead to dangerous situations.

Velocity⁚
* With pellets, the 760 Pumpmaster Classic can achieve velocities up to 700 fps (feet per second) with a full 10 pumps.
* With steel BBs, the velocity typically reaches around 625 fps.
Accuracy⁚
* The rifle’s smoothbore barrel, while contributing to lower velocity compared to rifled barrels, makes it relatively easy to achieve consistent accuracy at close to moderate distances.
* For optimal accuracy, proper aiming, consistent pumping, and quality ammunition are crucial.
* Target shooting enthusiasts often report good results with the 760 Pumpmaster Classic at distances up to 25 yards.
Factors Affecting Accuracy⁚
* Pumping Consistency⁚ Each pump should be applied with equal force for consistent velocity and accuracy.
* Ammunition⁚ The weight and quality of pellets or BBs can significantly impact accuracy.
* Sighting⁚ Proper sighting adjustments are essential for achieving accuracy.
While the 760 Pumpmaster Classic may not be a precision air rifle, its performance is suitable for various applications like plinking, pest control, and even some target shooting, especially with proper technique and practice.
