Default Meaning of 'Grain'

I'm a new shooter and when I purchase bullets I always see different types of grain. This could be a stupid question but does it mean the velocity of the bullet? How much powder the bullet has? I have a M&P40.

It specifically refers, in this instance, to the weight of the

projectile, or bullet.

Some standard weights for more common ammo which

you will see on store shelves:

9mm-115 or 124 grain

.223 or 5.56- 50,55,62,69 & 75 grain

45ACP-230 grain

44 Rem Mag-240 & 300 grain

30.06-- 150, 165,180 grain

It is also used, in reloading, to measure the proper amount of

gunpowder.

In any event, to help satisfy your curiosity further, I

can highly recommend any major manufacturer's

reloading manual. Hornady, Speer, and Lyman come to mind

as three excellent choices. Even if you never reload, it is a

goldmine of information for the new shooter.

BTW- 1 gram =@ 15.43236 grains.

7000 grains = 1 pound.

Which is heavier, 7000 grains of lead or 7000 grains of feathers?

It is absolutely not a stupid question. The only stupid question is the one not asked! Therewolf & Gatoragn gave you spot-on, excellent information. I might add that I like to think of a typical 9mm, 115 grain bullet as weighing just a smidgeon over a quarter of an ounce. Kind'a gives a little point of reference. Your typical .40 S&W bullet is just over a third of an ounce & the vaunted .45 ACP 230 grain hardball bullet is just over a half ounce.

Actually the feathers would be heavier on a scale.

Now that grains has been explained you'll want to consider that different grain bullets are going to move your point of impact and give you different recoil impulses. There is a lot of science that goes into the weight and shape of bullets.

As said, typically it will address the weight of the bullet. But if you get into reloading ammo, it will also address the weight of the powder (separate number)

Back in the day of black powder cartridges, like the 45-70, that was a .45 caliber fired by 70 grains of black powder.

In shotshells you may also find an archaic measurement of drams. Also a measure of weight, it refers to the EQUIVALENT amount of black powder that particular shell would have been loaded with to equal the current smokeless load.

Grain = A unit of measurement with regard to weight.

Beyond that, I'm probably ignorant as well. But I don't need to know more...because when it comes to units of measurement, things seem to fall cleanly into their respective place when comparing anything under the same unit scheme...regardless of whether you understand the finite details of said scheme.

Maybe I should know more. But it's just unnecessary.
