The 76 mm HE M352 (actual calibre is 76.2 mm) is a fixed round with the projectile crimped to the brass or steel cartridge case. One unusual feature of this round, and the other rounds in the US 76 mm tank gun series, is a crimped case over the projectile's specially designed drive band which has a groove to accept the cartridge case crimp. The 76 mm HE M352 projectile is a thin-walled steel forging with the interior filled with 662 g of Composition B. A PD or MTSQ fuze is threaded into the fuze well in the nose.
The cartridge case may either be an M88 (brass) or M88B1 (lacquered steel). The base-mounted percussion primer may be either the M58 or M68. A support spacer is located between the propellant and the base of the projectile. The propelling charge is 1.65 kg of M6 propellant. Muzzle velocity is 716 m/s and maximum range 14,338 m. The 76 mm HE M353 was originally developed for the 76 mm M1 series of guns, used on the M4 Sherman tank series and the M18 gun motor carriage. Later developments from 1947 onwards led to the 76 mm M32 gun for the M41 Walker Bulldog light tank series, the first of which was produced during 1951. The 76 mm M41 gun and its ammunition are no longer used by the US Army but remain in service with Brazil , Chile , Denmark, Dominican Republic , Guatemala , Somalia , Spain (reserve), Taiwan , Thailand (store), Tunisia and Uruguay. Some of these nations have updated their M41s to accept Cockerill 90 mm guns (for example Uruguay ). Applications include 76 mm M32 Cannon used on M41 light tanks.
