I have an antique 108 year old shotgun. References on the internet say to only use shells with "lead" pellets. I go to the local gun shop today and start looking for shells with lead pellets. I find: Copper coated lead pellets Nickle coated lead pellets Steel pellets Boxes with no pellet material specification The salesman recommended the Copper coated lead pellets I found that all of the boxes of shells in the size pellet I wanted, did not specify the pellet material. They have no pellet material specification on the entire box. I asked all the salesmen what the pellet material was in the unmarked boxes. They did not know what the pellet material was but told me it was "likely" the one I wanted. Typical salesman bullshit answer. Not knowing what to do? Any information will be appreciated.
