Depends on how big the difference is and the range.
Depends on the range, how big the variance and what brand you are using.
Grains are a unit of weight. Bullets, powder charges and brass casings are all measured in grain weight. So, yes there are different grain weights in reloading. There are also different powder grains, as in the texture of the powder. Those include, stick powder, ball powder, flake powder, etc...
None. Bullets generally do not contain gun powder. You may be thinking of a cartridge. Bullets are just chunks of metal.
There are a couple of different measurements. The weight of a bullet is normally expressed in grains. The diamater of the bullet is expressed in 10ths or 100th of an inch or in millimeters.
The .17 Hornady Magnum Rimfire (HMR) IS the name of the cartridge. It is a bottle necked rimfire cartridge- similiar to a a .22 Magnum necked down to .17 caliber bullet. Bullets used in this cartridge may be several different types, but are typically 20 grains or 17 grains in weight.
Range between 35-60 grains.
Most weigh ABOUT 240 grains, but can be more or less.
Grain is a measurement of weight. There are 7000 grains to 1 pound. Bullets can weigh from as little at around 20 grains to over 750 grains. Grain is also used as a measure of weight for gun powders.
Conversion: kg x 15,432 = grains
Bullets are measured in grains. 50 caliber rifle rounds typcially range from 650 grains to 800 grains. 50 caliber handgun rounds are typically around 325 to 350 grains.
"Bullet" only refers to the projectile which is propelled at a target, not the entire cartridge. A cartridge contains the bullet and gun powder and usually a case and primer. The "power" of a bullet is determined by its weight (or more correctly its mass) and its velocity, not by its shape or construction. Bullets can have weights from around 20 grains to over 750 grains (there are 7000 grains to 1 pound) and can have velocities of lower than 100 feet per second to over 4000 feet per second.
No. Grains per pound is the measurement of weight not volume. The volume would be different but the weight would be the same.
