Hey all of you experienced reloaders, I got asked a reloading question that I could not answer and I'm hoping one of you can help... On Federal brass (within the same caliber), some have head stamps that say "FC". Some have head stamps that say "FC 07" and others that say "FC 08". Is the brass the same or is it different? If there is a difference, what is it? "Thanks" in advance for any info you can provide. - browningbbr PS: The guy that asked me has .300 Win Mag brass with all 3 head stamps. He's going to weigh the pieces and let me know what he finds. I'll report on that when I get the info.
