5-In./54 Projectiles Type EX 23 Mod 1; Test of. Recovery Firing of 5-in. /54 Projectiles Type EX 23 Mod 1 in a Worn Gun
Abstract
Three 5-in./54 projectiles Type EX 23 Mod 1 were fired for spin and recovery from a 5-in./54 Mk 18 gun in the last quarter of its life, at a charge that gave 28 tsi (copper) proof pressure in a new barrel. This test was fired to determine the performance of the projectiles in a worn gun. It is concluded that the performance of the projectile Type EX 23 Mod 1 when fired in a worn gun (1358 ESR), at approximately 3050 ft./sec. velocity, is unsatisfactory because of excessive body engraving, yaw and erratic flight as noted by yaw cards.
