Many things can be smaller than a rock, such as a pebble, a grain of sand, or even a speck of dust.
It depends on how thick the Kevlar vest is.
A grain of salt does not equal 1 milligram; rather, it is approximately 58 milligrams. This discrepancy arises from the historical use of the grain as a unit of measurement in the apothecaries' system, where 1 grain is defined as 1/7000th of a pound. In contrast, the metric system defines 1 milligram as 1/1000th of a gram. Therefore, a grain of salt is significantly larger than 1 milligram.
An avoirdupois ounce is equal to 437.5 grains, while an international troy ounce is equal to 480 grains. It is based upon the mass of a single grain of cereal.

This means the weight of the bullet itself. A common misunderstanding is that the higher the grain the better. Which is not true. A larger grain is slower than a smaller grain. Find which grain of bullet shoots the most accurate out of your gun. There are 7,000 grains to a pound.
A .308 caliber 150 grain round zeroed-in at 50 yards will have a slightly high point of impact at 50 yards due to the bullet's trajectory arc. It will then drop below the line of sight around 100-150 yards before rising again, depending on the specific load and barrel length. At longer distances, the bullet will start to lose velocity and energy, affecting its terminal ballistics.
Winchester lists the ballistics of the ammunition it sells.
The .223 Winchester Super Short Magnum (W.S.S.M.) is a hyper velocity rifle Êround designed in 2002 for medium to large game hunting. There are three standard grain loads.ÊThe ballistic performance for the 40 grain bullet is 4,352 ft/s, for the 60 grain it's 3,733 ft/s, and the 75 grain is 3,378 ft/s.
The difference between a 40 grain bullet and a 36 grain bullet lies in their weight. The 40 grain bullet is heavier, which can result in higher velocity and potentially better accuracy due to increased stability. However, the 36 grain bullet may have a flatter trajectory due to its lighter weight.
Grain refers to the weight of the bullet when measured on a powder scale.
A grain is a weight. Smaller than an ounce or a gram- its a tiny amount. When talking about guns, grains refers to how much gunpowder is in each bullet. A bullet with more grains of gunpowder has more bang to it than a bullet with less grains of gun powder.
The weight of the bullet. They can range from 25 grain (Small rifles) to over 400 grain for big game.
Grain refers to the weight of the bullet when measured on a powder scale.
A 30-06 bullet fired at typical velocities will drop around 8-10 inches at 300 yards depending on the specific load and ballistics. It's always recommended to verify with a ballistics calculator or actual shooting to get accurate results for your specific setup.
The bullet drop for a 30-06 150 grain bullet at 200 yards will vary based on the muzzle velocity of the specific load being fired. On average, you can expect around 6-10 inches of drop at 200 yards, depending on the specific characteristics of the ammunition and rifle being used. It's best to consult ballistics charts or use a ballistic calculator for a more accurate estimation.
