I assume you are asking about the 760 pumpmaster XLS. Their are 9 different variations of the 760.
The Crosman 760 is a BB repeater or single shot 177-pellet rifle. But your question is how do you shoot it?
Load the rifle with either a Pellet or BB. Pump it several times NOT more that 10 times. Usually 8 pumps is more than enough. Aim at your target grip the rifle fairly tight in your right hand but do not grip it tight in your left hand (Hold it easily with your left hand.) Air rifles have a different kick than regular gunpowder rifles. Holding it tightly in both hands will cause you to pull off target. Relax and take a deep breath and breathe out slowly. Aim at your target using the sights. Squeeze the trigger. Do not yank the trigger or it will pull you off target. Once the rifle fires keep you sights on the target. (Basically follow through with your shot) adjust your next shot to compensate for any variations that you made on your last shot.
The 760 is a smoothbore barrel rifle (most all BB rifles are smooth bore) so it is not as accurate as a rifled bore Air Rifle. ) However with practice you will get better at knowing you rifle, so keep practicing.
