Beeman usually has the Model number on the side of the barrel by the loading port or on the barrel by the hinge on break barrel rifles.
A .177 caliber air rifle has very little recoil.
Air rifle ammo is as simple as a BB. the next ammo is a Pellet. Pellets come in different sizes and weights. The size calibers are: .177, .20, .22, .25, .357, 9mm, 45 caliber and finally 50 caliber.

Beeman makes several good air rifles & guns. I know of 3 different "Sportsman SS" series that shoot .177 pellets And the RS1 Sportsman that comes with 2 barrels .177 & 22. But I know of no Beeman Air Gun called Sportsman. Just the Sportsman Rifle. If you are talking about the RS1, then yes I would have to say it is a good rifle for the price.
I suggest you contact Beeman directly and ask your question: they make several different models. Beeman Co 10652 Bloomfield Ave Santa Fe Springs, CA 90670 Ph: 562-968-5891
