Evaluation of Two Blank Firing Attachments for the M2HB Caliber .50 Machine Gun

Abstract

Firing tests were conducted using an M2HB Caliber .50 Machine Gun equipped with blank firing attachments (BFA) fabricated at Ft. Benning and Ft. Carson. Two BFA of each design were tested. Both designs operate on the muzzle booster principle. Three lots of blank ammunition were tested and one lot of M33 ball ammunition was fired to provide a base line for comparison of weapon mechanism performance. All of the existing blank ammunition including those lots tested were loaded in 1943-44 or in 1953. Because of its age and the way it was packed and stored the performance of individual rounds has deteriorated and varies widely down to refusal to fire. Although the erratic ammunition performance prevented quantitative accuracy in evaluation of test results the data did provide a basis for engineering evaluation and a recommendation that a coordinated program of ammunition and BFA development be considered for early implementation.
