Unlike regular HE, these shells will have to penetrate at least 7 mm of steel in order to deal damage, and then will explode only after 0.015s, which translates to nearly 13 meters. That is 4.26 meters deeper into the ship's hull than the SAP shells. That effectively means that shells can over-penetrate a number of destroyers (like [[Shimakaze]] with 11 m beam) and frigates (e.g. [[SKR-7]] with 9.2 m beam) when hitting them perpendicularly across the hull, if it won't encounter any module inside of the ship. But a longer travel distance can be used to an advantage, when dealing with the unarmoured sections of a cruisers, such as the [[ammo racks]] on [[Kuma]].

 '''M1924 SAP''' is a shell dedicated specifically against an armoured targets. It will explode after penetrating at least 7 mm of steel, traveling up to 8.7 meters into the hull. SAP shell features much a higher penetration at a 0° {{Annotation|AoA|Angle of Attack}} and over 25% larger explosive filler than the base fuse shells. But against an angled targets the base fuse shells offer a nearly identical penetration (1 to 3 mm difference across the range for 30 and 60° {{Annotation|AoA|Angle of Attack}}) yet is far less likely to ricochet - while striking the target at 71°, the SAP shell has 100% ricochet chance, while the base fuse shell still has a 0% ricochet chance. These ricochet values are typical for the SAP shells across all nations.

 Overall it makes SAP shells far more suitable when hitting the flat armour at a minimal angle, e.g. when shooting at the targets on parallel course, while the base fuse shells are better used against angled ships, e.g. when [[wikipedia:Crossing the T|crossing the T]].

-mm/50 model 1920 is perfectly capable of dealing with a majority of the targets it will encounter in its BR range. It's more than capable of ammo-racking any destroyer or early light cruiser and has a respectable damage output. Low muzzle velocity makes it tricky to hit maneuvering targets at distance, but it also makes it easier to hit the targets behind a hard cover, or dive shells into the ammo racks at longer ranges. Where it struggles are armoured targets, especially heavy cruisers at range if they do not have unarmoured ammo racks. This makes vessels like [[Prinz Eugen]] (BR {{#unit:germ_cruiser_prinz_eugen|br}}) extremely difficult to counter without the help of other ships.

 The most apparent feature of this gun is its low sustained rate of fire. While its 17 ready-to-use shells are fired at a low, but acceptable 6 rounds per minute, the sustained fire rate of just 4 shells per minute is more typical for a battleship than a cruiser. The [[6 inch/47 Mk.16 (152 mm)|US 6 inch/47 Mk.16]] features a 150% higher rate of fire.
-This, to a degree, is offset by a large explosive filler of the shells. SAP shell with its 3,67 kg filler can output above-average 14,68 TNT equivalent per minute, nearly a double of [[150 mm/45 SK L/45 (150 mm)|150 mm/45 SK L/45]], yet significantly behind the [[152 mm/57 B-38 (152 mm)|152 mm/57 B-38]]. HE shells on the other hand are below average, and the base fuse HE shells have some of the lowest TNT equivalent per minute for among the HE shells, but only below-average among the armor and semi-armor piercing shells.

While loading mechanism was largely electrically powered, it still failed to achieve a higher rate of fire than the 203mm guns of the era.
+Guns used loading mechanism derived from the French battleships. Two hoists provided shells and propellant to the work room below the turret itself, which were then transferred directly into the turret right next to the gun breeches, where they were transferred to loading trays and rammed into the breech. While loading mechanism was largely electrically powered, it still failed to achieve a higher rate of fire than the 203 mm guns of the era.
 Turrets themselves were the world's first to have a fully electrically powered training angle and elevation.
