Granulated rubber berm type traps should be scheduled for lead reclamation servicing around the 75,000-round count per lane.  This maintenance can be completed by the range owner (using the correct safety equipment and procedures for handling lead) or contracted with a professional lead reclamation company. 12 to 18 months between lead reclamation services is a good average to expect. As settling occurs (at initial filling and at lead reclamation) additional rubber may need to be added to replenish optimum levels. Rubber block type traps generally will take up to 5,000 rounds per block before needing to be replaced.
