Is there a preference on which brass is used when reloading 9mm ammo? I was talking to my dad the other day and he has an old (20 yrs or so) reloading book that says not to use anything but Speer brass for some reason. He mentioned something about the crimp too, I've done a bit of reading and forwarded him a bunch of threads about the crimping issue. But didn't ever come across something that commented on different brands of brass. If you guys have any info I would really appreciate it. PM me if you have any tips how to get the crimp adjusted right or any other tid bits on reloading. If we could keep this thread on which brass takes reloading better I think it would keep things a bit cleaner here in the Ammo Can. Thanks in advance guys.
