You need a set of o-rings and seals for it. Try Pyramid Air.

The only Beeman Sportsman Rifle I can find takes either .177 or .22 caliber pellets depending on which barrel is fitted.

If the pellet you tried was a .177 try a .22.

Otherwise try emailing [email protected] and see what they say.

If your pumping the rifle and you hear air seeping out then the seal on your air chamber is bad or got pushed from where it is suppose to be, you can take it apart and see, its real simple...

Are you sure its a bb gun and not a pellet gun? Usually bb guns have a magnet on the bolt, that keep the bbs from falling out. Pellets don't roll so the won't roll out the barrell.

you have a triger fault its not locking the piston back best and safest bet is a gun smith,, never play with a triger if your not good with guns,

clean it, if that doesn't work they have adjuster between the power selector and the tube of the scope
