when people talk about grain I dont understand what they mean.
grain is a measure of weights used almost exclusively in firearms. 1 grain (1gr) = 1/7000th of a lb.
Bullet weight is measured in grains. There are 7,000 grains in a pound.
edit: damn you
I see what you did there...
The other thing that makes it confusing is that bullets are weighed in grains, but so is the powder charge in the round.
I would think that makes it simpler? Two different units of measurement would only make things more confusing.
what makes it confusing is that with powders, not all grains are created equal, since some burn faster than others
It does make it easier once you realize that it's just weight. If you don't get that, then it's confusing because you're talking about 2 different things (powder vs bullet) using the same word.
I dunno, I've always taken it for granted that when you're talking about powder loads, the type of powder is just as important as the amount used.
and if you're new to the whole discussion, you might think (I know I did, when I was just starting out) that 'grain' refers to the granule size of the powder, like 'grit' does to sandpaper.
If you're buying factory ammo powder weights will probably never come up unless you're buying reduced recoil loads or hotter loads and even then they aren't going to give you the weights.
Or something like a .30-40 Krag, or .45-70 Gov't
