Solid Lead Bullet

Minié ball - Wikiwand

"Laws of War" of Hague Peace Conference in 1899 banned the use of solid lead bullets, which expand or flatten easily in the human body, transferring most of its kinetic energy to the target and causing grievous harm.

Jacket and Penetration

Lead round will melt in the barrel, harder metal is used to wrap the round.

Full Metal Jacket (FMJ) round

The lead tip is fully covered, the shell will keep its shape upon hitting the target. This has the most penetrative. It is also called NATO rounds.

Controlled Expansion round

The lead tip is not fully covered by the jacket so the shell expands to a mushroom shape upon hitting the target. This is used for hunting and create a massive cavity on the point of impact.

Fagmentation round

The lead tip is even covered less by the jacket, so the shell break into fragments upon hitting the target. It will not penetrate more than 12 inches into the target.

Magazine

Magazine can be detachable or housed within the gun.
Benefits of detachable magazine:

the whole clip is replaced
there's no need to reload the rounds one by one
and the magazine are easier to pre-manufacture
variable magazine size
built-in magazine have a size fixed at the design time

Why use clips when you can use magazines? - YouTube
However magazine are more expensive, creates extra loads for soldiers and take more volume than clips.

Reloading

Mussel loading: the shooter have to stand up and use a stick to push gun powder and the lead ball to the end of the chamber.
Lever Action (mid 1800): cork a lever to eject empty shell and load new round to the chamber. The lever is usually pulled downwards from the barrel, meaning that the shooter have to ensure vertical clearance when reloading.
Bolt Action (mid 1800): the lever is replaced by a bolt that moves along the axis of the barrel.
Recoil Action (mid 1900): the expanded gas in the barrel is used push the lever to eject the spent shell and chamber the next round (which is equivalent to the the bolt action, however, no manual action is needed). You fire one round per trigger pull. First applied in Maxim machine gun.
Blow Back Action (mid 1900):
Fully Automatic: load, pull and hold the trigger until your magazine is empty. Advanced design will also route the exhaust upwards to suppress the recoil.

Trigger (firearms) - Wikiwand
Single Action: the trigger only releases the lever, the lever has to be manually loaded
Double Action: the trigger pulls the lever back and releases it
Single action triggers should provide more accuracy (as the aim is not affected by the sudden release of the spring)

MMG and LMG fires rifle calibers (.30-.40).
MMG is mounted on tripod and uses ammo belt.
LMG can be shoulder or bipod mount, uses ammo belt or magazine (Chauchat, Lewis).
HMG fires heavier rounds, mounted to tripods and vehicles.
SMG fires pistol calibre cartridge, have less recoil.
GPMG (general purpose machine gun) are invented after WW2, .30 caliber, work on mounts or handheld, quick change barrel, uses ammo belt (MG42, PK/PKM)
SAW (squad automatic weapon)/LSW (light support weapon)/automatic rifle (M1918, M1916A6, RPK/RPK-74, M249, LSW) uses same magazine to simplify logistics
Modern HMG, .50 caliber (12.7-20mm), anti-material and anti-vehicle

smoothbore is preferred for APCR and APDS

Kinetic shells pierce the armor via kinetic energy:
穿甲彈 (Armor Piercing, AP): pierce armor with hardness and momentum, with explosives inside to further damage crews, 尖頭穿甲彈 can easily be deflected with inclined armor
被帽穿甲彈/鈍頭穿甲彈 (Armor Piercing Capped, APC): cap made of softer steel added, it will deform and normalize the shell to reduce the armor thickness needed to penetrate
風帽被帽穿甲彈 (Armor Piercing Capped Ballistic Capped, APCPC): 被帽穿甲彈 is more effective but not aerodynamic; 空心風帽 (Ballistic Cap) is added to reduce drag
Armour-piercing, capped, ballistic capped shell - Wikiwand

Sub-calibre AP rounds have smaller and denser core (碳化鎢), using larger barrels also allows for greater initial velocity, they create less spalling and shrapneling:
高速穿甲彈 (High Velocity Armor Piercing, HVAP)/硬芯穿甲彈 (Armor Piercing Composite Rigid, APCR): smaller caliber core inside the aerodynamic jacket will pierce armor after contact
脫殼穿甲彈 (Armor Piercing Discarding Sabot, APDS): the aerodynamic jacket will decouple with the small and dense core shortly in-flight
尾翼穩定脫殼穿甲彈 (Armor Piercing Fin-stabilized Discarding Sabot, APFSDS): ammo fired without spin (with smooth bore barrel) to accommodate lengthier ammo, the ammo is stabilized with fins like a dart; also adapted to rifle barrel but usually only used in small caliber
Armour-piercing fin-stabilized discarding sabot - Wikiwand
尾翼穩定脫殼穿甲彈 - Wikiwand

Chemical shells contains explosive filler that will explode on timer, on contact or by proximity.
高爆彈/榴彈 (Armor Piercing High Explosive, APHE): explodes after penetration, the shockwave and shrapnel deal AoE damage; not useful for AP due to reduced mass; also have BC, CBC variants; also used for Anti-Air shells
高爆彈_百度百科
破甲彈 (High Explosive Anti Tank/HEAT): contains explosives and an (inverted) metal cone, the explosion happens outside of the armor and the shockwave will form focused a jet of metal particles at supersonic speed to pierce the armor and wreck havoc; smooth bore barrel should be used to keep the jet focused; initial velocity is irrelevant; needs room between the explosion and the armor for the jet formation, as seen by the standoff probe in the front to detonate the explosive; also have BC, CBC variants; used in RPGs; aka HEAT-MP (Multipurpose) or MPAT (Multipurpose Anti Tank)
尾翼穩定破甲彈 HEAT-FS: Since we're not using rifle, fin stabilizer is used, also reduces the weight of shell
碎甲彈 (High Explosive Squash Head, HESH/High Explosive Plastic, HEP): contains explosive that will deform, spread and stick to outside of armor, explosion will send shockwave through the armor and create spall and shrapnel inside to injure the crews; prefer rifle barrels to spread the HE; used by UK so they tends to keep Challenge 2's rifle barrel
Armor Piercing Incendiary round

Anti Anti-Armor

反應裝甲 (Explosive Reactive Armor, ERA) and 間隙裝甲 are used to counter 破甲彈, 碎甲彈.
Ceramic composite/Kevlar liners armor also nullified application of them.
Twin-staged warhead (Tandem-charge) is used to counter ERA where the first stage (precursor charge) will detonate/destroy the reactive armor.
Second gen ERA have two set of explosive and steel plate to counter that. Think of Cheese Burger vs Big Mac. The two plates are set grind together, effectively increasing the thickness and can also snap APFSDS.
Heavy ERA have multiple charges that shot out to destroy the incoming round. But this is not welcomed by the infantry cause the extra charge may cause harm to surrounding troops.
