A quotation detailing the cost of redirecting efforts from the XM502 to the XM570 BMC was submitted to Picatinny Arsenal. Mill certifications showed that W1 steel carbon content was 1.27, above the specified 1.1 to 1.2. The deviation was allowed. Mill reports and local tests showed that high carbon, high phosphorus steel bars were unsound in the center. The material will be used to check effects of this condition. Four experimental heats of A1S1 06 steel were received, cost-free, for tests. Manufacture and heat treatment of all cylinders neared completion. Work centered on preparation of metallurgical test specimens from heat treated cylinders. Fragmentation testing was completed on two cylinders each made from 52100, 06, 1095 and 9261 steels. Very little activity was expended on the projectile due to the possibility of changing contractual models.
