Abstract : Notice was received that the XM570 (BMC) will be the contractual round. Cylinders were made from high carbon, high phosphorus steel bar. These and cylinders from W1 tool steel were sent to a subcontractor for heat treatment. 52100 steel cylinders were heat treated to replace items inadequately heat treated during November 1965. Metallurgical tests continued. Difficulties encountered in sectioning very hard cylinders prompted a search for better cutting techniques. (Author)
