How is gun powder measured?
The only way to do this is by measuring the powder charge. When black powder was the only powder shooters used, it was most often measured by volume. Due to the burning characteristics of modern smokeless powders, it should be measured by weight. However, if done carefully, it can also be measured by volume.
Is gunpowder measured in grains or grams?
These days, the grain is most commonly used to measure the mass of bullets and gunpowder. It can refer to a single grain of gunpowder – but as a weight this can vary depending on the type of powder being referred too.

Do you measure every powder charge?
At typical shooting distances, a properly functioning powder measure works fine. But for longer ranges many handloaders prefer to weigh every charge for best accuracy. The only way to be certain each and every powder charge in a batch of cartridges weighs the same is to carefully weigh them on a scale.

What is the difference between a 150 grain and 180 grain bullet?
The top speed from a 180-grain bullet was 2,770 fps. At those speeds, and with both bullets sighted in 2-inches high at 100 yards, the difference in drop between 150- and 180-grain bullets is 2.82 inches at 300 yards, 5.73 inches at 400 yards and 9.69 inches way out at 500 yards.
What does powder charge mean?
: the charge of powder for propelling a projectile.
How do powder measures work?
