rifle bullet
Assuming you mean the slug as a form of shotgun load, then, it depends. The slug is significantly heavier than a typical .30 caliber (7.62mm) rifle round, and the sabot nature of the slug load for a shotgun produces a reasonable amount of muzzle velocity (though, less than a quarter that of a typical rifle).
Due to the nature of shotguns, and the lower initial velocity, the slug has significantly shorter range (100m, maybe) than a typical rile (which can be used up to 1000m). Inside that range, however, the slug has enormous energy.
The effectiveness of the slug vs the rifle bullet really depends on the type of target being shot at. The small cross-section and very high velocity of the rifle bullet make it good for punching through thin but strong materials (kevlar, lexan, steel), but poor for thicker materials (including tissue, where rifle bullets tend to make a small hole straight through, but cause little extra damage). A slug's big diameter, much slower speed and high mass make it excellent for penetrating layered materials (e.g. a car doors, masonry, etc.), plus, it causes massive tissue damage.
have a gunsmith do this, push a slug of close dia through the rifle, and micrometer the bullet. this will give the true bore size.
rifle slug regular slug
ammunition means "to be fired from a gun" so slug ammunition means they use it as a bullet ,or with one ,or maybe they have a bullet as a shape of a slug
Slug could be a snail like animal. It could also mean one heavy bullet.
of Slug
Mainly it's the ballistic trajectory. With a shotgun, if you want to kill a deer, you will need either a slug, or buckshot. The slug (or combined weight of the buckshot) is heavier than a bullet from a rifle, and they move slightly slower, making their range more limited. Especially with buckshot. Also, there is no rifling on the barrel, so the projectile(s) from a shotgun are less stable. A rifle bullet goes faster and longer before becoming inaccurate.
No standard abbreviation
A rifle fires a single bullet or round such as a 7.62 or 5.56 millimeter. A shotgun fires a slug such as 12 gram that consists of multiple projectiles. Also a rifles barrel has rifling (or groves) to put spin on the bullet when it is fired.
Yes, any bullet can kill you. The amount of damage a bullet does depends on several factors, basically: where it hits you, how hard it hits you, and how big the bullet is (or how much it expands).
No, a sabot slug does not rise after it leaves the barrel of a gun. No bullet rises after it leaves the barrel of a gun. It always falls from the line of sight of thebarrel. All firearms have to be "sighted in" a bit high to hit a target downrange. At close range, there is little time for a bullet to drop and hit "low" on the target. Down range, however, the drop is more significant. The more time a bullet is in flight, the more it drops below the line of sight of the barrel. But a bullet always begins to drop below the line of sight of the barrel after it leaves the muzzle. Always.
The .22 WRF uses a larger case, and has a slightly larger bullet diameter (.224, as opposed to .223). The .22 WRF uses a flat nosed slug, as well.
The 410 is a shotgun round. Slug loads are available and have been made for decades.
