This is a great thread. Thanks for posting your collection.
I'm relatively new to collecting calibers (started in 1999), and it is more of a passive hobby. I usually pick up brass whenever I'm out at a range and sometimes acquire brass and oddball cartridges through friends that know I collect.
Not to hijack the thread, but I have a question for everyone. In your experiences, what is the best way that you've found to identify old or uncommon head stamps on odd ball cartridges? ...other than a google search.
I've used such sites as http://cartridgecollectors.org
