Yes, there are .20 cal bullets. Not very common, they are typically very small bullets for high velocity rifles. The Ruger .204 is about a .20 caliber cartridge.
Also known as the .32 Winchester Center Fire, the 32-20 cartridge was used in revolvers and light rifles. It's name indicates that it fired a .32 caliber bullet, originally loaded over 20 grains of black powder.
20 miles every 2minutes very fast
The distance a bullet will travel is almost completely dependent on the size/weight of the bullet, and the velocity of the bullet as it exits the end of the barrel. For instance, an average .22 caliber bullet shot from a revolver with an average barrel length (12.7 cm) can easily travel one kilometer and still be relatively accurate, and -- if the angle the gun was pointed and other given conditions are right -- up to two kilometers. Generally speaking, the larger caliber the bullet, and the smaller the exiting velocity, the slower -- and therefore shorter distance -- the bullet will travel. If you are asking for an effective kill distance for a revolver, that will predominantly depend on your skill with said revolver. If you can accurately shoot up to 200 meters with the revolver, then that is your effective kill distance. If you are only accurate up to 5 meters away, then that is your effective kill distance. The average individual with minimal training can typically hit 80% of shots taken on a body-sized silhouette at 20 meters.
Velocity of .50 BMG (Browining Machine Gun, 660 gr to 720 gr bullet weights ) projectile within 20 feet of the muzzle will between 2750 and 2850 feet per second, depending upon the cartride.It depends on the weight and shape of the bullet, as well as the amount of powder used, but a good average would be from 2800 feet per second to a little over 3000 feet per second when shot from a rifle. There have been reports of greater speeds (in the 4000 to 5000 fps range) perhaps with sabot rounds.
Depends how fast you are traveling. On a highway,about 15- 20 min.
A heavy duty rubber band will travel about 50-70 mph in its first 20 ft of travel.
Generally, a bullet's caliber has NOTHING to do with its accuracy. So your question cannot be answered. However, a 9mm is usually a handgun round, used at close range (0-15meters). A .223 is typically used at longer ranges, but could be used close-up as well. At distances greater than 20 meters, up to 500 meters, the .223 will be more accurate, if the weapon is dialed-in.
Caliber is the measure of th internal diameter of the barrel in inches- a .30 caliber gun fires a bullet that is about 30/100ths of an inch across. European guns are usually measured in millimeters- a 9mm fires a 9mm diameter bullet. Bigger number equals bigger bullet. GAUGE is an older term used to measure the internal diameter of a shotgun barrel. It came from the number of round lead balls that fit the barrel that add up to one pound. So 20 balls in 20 gauge weigh one pond, 12 balls in 12 g weigh one pound, etc. SMALLER the gauge, bigger the barrel. The .410 shotgun is the exception- that is really .410 caliber.
Bee's travel at about 20 MPH on average. Slightly faster when conditions are perfect.
