So, use both and switch out based on tactics needed to win the fight. A machine gun, just because of recoil will not be accurate over a larger distance, whereas a rifle will be more accurate at a distance, and carry more kinetic energy when it gets there. When you have time to take aim and choose your targets, it is because they are farther away and you have the time to do so, that is when you want one bullet to do as much work as possible. The fact that there is less energy being applied to the target per round is offset by the fact that more rounds will land on target. When your fighting a bunch of people close up, you want to spray as many bullets into the crowd as you can to cut down as many enemies as possible in as short amount of time as possible, and a machine gun is ideal for that. I will ignore ballistics and physics and kinetic energy here. Lets look at this from a practical standpoint.

True, an old lady actually took out one of the largest bears with a single shot.

The mutated bears in Fallout are definitely pretty strong then. I mean in real life regular bear can be stopped with a single decent shot. Many other things matter.īye the way 5.56x45mm NATO replaced 7.62x51 NATO which was MUCH stronger round. Still, a fully modded Assault carbine GRA depletes their health quickly. This is very tricky and not as simple as just calibre comparison or muzzle energy. Especially because low calibre military ammunition have hard jacked and do not deform as much upon impact as soft projectiles of larger calibre. That is where larger calibre ammunition have advantage over low calibre. Energy have to be transferred in to target, otherwise its useless.

lbfġ0mm is a pistol round that has a low muzzle velocity, 5mm is a fictional rifle round that supposedly replaced 5.56x45mm NATO so I would imagine it would have superior performance.Įnergy alone is as useless as diameter alone in determining its effect on target.

Real 10mm AUTO has a muzzle energy of around 750ft The diameter of the projectile has little to do with how powerful the round is.
