Daisy CS told me that BBs won’t hurt rifling.

Although BBs are much less expensive than pellets, they have some disadvantages. First, a steel BB can not be designed to fit tightly in the bore. As a result, accuracy of a particular rifle is not as good when shooting BBs as when pellets are used. Pellets are made of lead or a lead alloy so they are soft. They can be made to fit the bore by being swaged slightly as they are fired. Therefore, they fit the rifling better, and the result is better accuracy. Another disadvantage of firing steel BBs in a rifled barrel is that the BBs do not engage the rifling but rather ride on top of the ridges. Prolonged use of BBs in a rifle barrel can cause the tops of the rifling ridges to be worn off because unlike a lead pellet, a BB is as hard as the rifle barrel itself. If this happens, the rifle probably will not shoot as accurately with pellets as before the abrasion occurred.
FYI: Gamo makes lead BBs.
