Why are there so many gun models using the same calibre? Doesn’t the bullet determine most of the lethality and range, while the gun is just the vehicle that fires it?

If the shooter isn’t comfortable, they’re not going to shoot straight.

If the machinery of the gun rattles around during operation, it’s going to affect machinery.

Longer barrels = more time in the compression chamber = faster/straighter bullet. Mosin Nagant rifles were extra long so they could double as a spear/pike line against cavalry charges while being accurate out to 2km.

Shorter barrels = more concealment/portability so you can force march 20 miles and sneak it into the meeting.

Heavier weapons are nice because they don’t recoil as much (accuracy), plus if you run out of ammunition you can just hit somebody with it.

Light triggers make for accurate shooters – and accidental firings with stupid shooters.

Plus, guns that look cool sell better than guns that don’t.
