The Stielgranate 41 looked like a
rifle grenade, only considerably larger. One part of its stem, a long stick, was placed inside the gun barrel; the other part, a perforated tube with six stabilizing fins was fitted around it. The tube held the grenade in place until it was fired, while the perforations extracted the maximum performance from the propelling hot gases and prevented excessive blow-by. According to Chamberlain, it was fired using a standard cartridge case containing of
nitrocellulose, while Hogg gives a figure of of Ngl R P, with a cork plug sealing the mouth of the cartridge. It was equipped with two
fuzes: the AZ 5075 (
Aufschlagzünder 5075) in the nose, for direct hits, and the Bd Z 5130 (
Bodenzünder 5130) in the base, to ensure detonation if the target was only grazed. The large caliber of the
High-explosive anti-tank (HEAT) warhead and shaped charge containing of
cyclonite and
TNT, enabled it to penetrate armour thick, enough to defeat any World War II tank. The hit was equally dangerous at any distance, as the
shaped-charge effect is not dependent on the velocity of the round at the point of impact. However, the low velocity of the grenade − − limited effective range against tanks to or less. While it was originally designed for use with the Pak 35/36, it was also used with captured French
47 mm APX anti-tank guns, while a Czech-designed version was used with captured
3.7 cm KPÚV vz. 37 and
4.7 cm KPÚV vz. 38 guns. ==Performance==
