    Yep!
    However do no confuse Black powder cartridges if you see them in a load book.
    45-90-110
    45-120-3.25
    50-140
    etc.
    Different critter.

    Both, a grain is a measurement of weight equal to 1/7000th of a pound. A 40gr slug for a 22LR weighs as much as a 40gr powder charge for a rifle.

    Johnny45-
    Kingjoey's statement is fact. However, since you're asking the question I will assume that you are not terribly familiar with firearm terminology. So allow me to clarify based on the content of your question: On factory ammunition, the grain measurement number listed refers only to the bullet; no manufacturer (to my knowledge) lists either the type of powder of charge weight. So if the box reads ".45 ACP 230 gr. JHP", it means that the bullet is a 230 grain jacketed hollow point.



    Save the seals-club a liberal instead.

    So which weighs more;
    A pound of lead or a pound of feathers?

    I kept thinking about mentioning that but I didn't want to confuse the issue[:D] That statement alone often has folks debating and scratching their heads around here[;)]

    okay, so the grain weight listed on the box refers to the part that is shot out and impacts the target. thanks for the info

    Correct Johnny. The grain weight listed on the box is the grain weight of the bullet.....and the bullet is that lead thingy goes down the barrel. [:)]

    This often gets confooooozin' because sometimes people say bullet (that lead thingy) when they mean cartridge....and a cartridge is that thing you put in a gun to make it go boom! It consists of the cartridge case, primer, powder, and bullet....all stuck together in one neat package. [:D]
