Never more than 10 pumps. I only use 8 pumps to be safe. More than 10 will damage the rifle over time.
This rifle is a break barrel design an shoot one pellet at a time and has to be reloaded after each shot.
Never more than 10 pumps. Anything between 1 and 10 will discharge the pellet.
Sterling has not been in production for many years. They are no longer available through normal channels.

The Chinese B-3 is rated at 450 FPS by the Manufacture. This is considered to be slow in the world of .22 caliber air rifles. As an example the Hatsan model 95 fires a .22 caliber pellet at 800 FPS and a Crosman Nitro Venom fires a .22 cal pellet at 950 FPS.

Answering this question is not as simple as it sounds. I suggest you read the attached link ( http://www.straightshooters.com/general-airgun-information.html) it gives some great information about effective ranges with a .25 caliber pellet. Also I applicate the statement that a .25 is big bore pellet. Unfortunately it is considered small bore. A big bore would be a .45 or 50 Caliber pellet. Also remember that the air rifle power plant has a lot to do with the range. I own a .25 cal Hatsan break barrel and a .25 Caliber Condor PCP air rifle. Obviously the Condor has a further range than the Hatsan. This is why manufactures don't publish the range of the air rifles. there are just too many factors to consider like Barrel length, Weight of the pellet and power plant of the air rifle.
Are you asking about a Benjamin model 177. If so, then never more than 10 times or it will blow and ruin the seals.
