I don't even shoot matches and i have all the 9mm brass I'll ever need. Even at the public outdoor range there is plenty of 9mm brass on the ground.I'd agree with Walkalong. I've never actually purchased 9mm brass -- it just appears by the bucketfull, especially after large matches -- and I've never owned a piece long enough for it to wear out. I've found some that cracked, or were too loose for the primer and they get recycled.
