Experimental muzzle brake performance tests were carried out at reduced scale, using a 40mm free-recoil gun apparatus, for comparison with available 105mm data. Results were sufficient to conclude that muzzle devices can be accurately investigated and developed at reduced scale, with considerable savings of time and money. The apparatus and procedures developed are, with minor modifications, satisfactory for carrying out reduced scale testing.
