I hate to ask rookie questions but I just don't get it.
What is the grain number when dealing with ammo? I've seen 9mm have 115/124/147/etc and 45 ACP have 185/200/230/etc. What does that mean? Is that the amount of gun powder in the casing? I thought that's what it meant until I started looking at prices and saw that Speer had some round cost more when they were lower grain. Wouldn't it cost more for higher grain? More gun powder afterall?
I was just wondering and couldn't find an answer that seemed correct.
